FAQ Rental cars: Your questions, our answers

Vehicles with four-wheel drive are marked with a "4x4" icon and labelled "four-wheel drive". You can also specify this using the "Equipment" filter when searching, if available for your destination. 

If it’s already clear that more than one person will be driving the car, we recommend booking a rate that includes an additional driver right away.
During vehicle selection, simply click on the "Additional driver" filter – this will show only offers that include this service.

If the service is not included, it can often be added for a fee on site. You’ll find the exact costs for the additional driver in the specific rental conditions.

Make sure that both the main and additional driver sign the rental agreement including the special rental conditions, so that our all-round carefree package applies to everyone.
Important! The additional driver must be present in person when picking up the vehicle and must bring both their original driver’s license and ID card or passport.

To ensure that your holiday does not begin with long queues at the rental car counter, we recommend our online check-in: Simply activate the "Online check-in" option in the booking menu under "Popular filters". Before you start your journey, you can submit all the relevant IDs and driving licence details so that the rental agreement is ready for you to sign at the rental company. You will still have to queue, but you will avoid the time-consuming process of filling out forms on site and will be on your way more quickly.

If you choose a rental car with "Express Pick-up", "No Deposit" or "Young Car", you will automatically receive online check-in at no extra charge. 

The number of people specified is a recommendation based on space and luggage capacity. Vehicles from the compact class upwards are usually suitable for 5 people. For smaller categories, we will be happy to check individually – please contact us by email at info@sunnycars.de or by phone on 089 / 82 99 33 900. 

Whether you are selecting a vehicle, viewing insurance options or making a payment, the specific rental conditions are just one click away throughout the online booking process:

Once you have completed your booking, we will automatically email you the same documents together with your voucher, so that you can access them at any time. If you have any questions, please do not hesitate to contact our customer service team.

At Sunny Cars, you always book a vehicle category – not a specific model. The exact engine type cannot therefore be specified in advance, as our local rental car partners regularly update their fleets and individual vehicles are replaced, e.g. due to defects or accidents.

There may be a technical glitch – please refresh the page. If that doesn't help, there may be no vehicles available at the selected location during the desired period.

For support, please use the chat function, call us on 089 / 82 99 33 900 (Mon–Fri 9 a.m.–8 p.m., Sat–Sun 10 a.m.–6 p.m.) or send us an email at info@sunnycars.de.

We apologise for the error message on our website. Please send us a brief email to info@sunnycars.de – ideally with the error code displayed or a screenshot of the error message. This will enable us to investigate and resolve the issue as quickly as possible.

Our discount codes are usually subject to certain conditions. You can find detailed information on this on our website under "Tips & Promotions". If you are unsure or have any questions, please feel free to contact our customer service team on 089 / 82 99 33 900. Please have your booking number ready, if available. 

As a rule, we receive feedback from our local car rental partner within 24 hours of your booking. Please note: For requests regarding optional extras, on weekends or during periods of exceptionally high demand, it may take up to 48 – 72 hours in rare cases to receive a response from the destination.

Rest assured – we keep a close eye on every open booking and the scheduled pick-up date, and we’ll contact you proactively as soon as we receive any updates from the destination.

Thank you for pointing this out! The prices shown always include our all-inclusive package. This means: full insurance cover, transparent conditions and reliable service – with no hidden costs on site. If you have any questions, please contact our customer service team on 089 / 82 99 33 900.

If customers do not show up at the counter or at the meet & greet point at the agreed time, the booking will be considered a "no show". As the vehicle is reserved exclusively for you during this period, we will charge 100% of the cost in this case. Therefore, please notify us of any delays or changes in good time. 

If no damage is identified when the vehicle is returned, the deposit will be automatically released or refunded. Depending on your bank, this may take 24 to 48 hours. In some cases, the transaction will only appear on your next monthly statement.

As soon as the vehicle is returned without damage, the rental company will initiate the release of the deposit. Depending on the processing bank, it usually takes one to two days for the amount to become available on your credit card. The release is often only visible on your account with the regular monthly statement.

Of course! Sunny Cars only transmits personal data via SSL (Secure Socket Layer). This technology encrypts all information so that it cannot be viewed by third parties during transmission. Access is restricted to you and the server, ensuring secure and confidential processing.

With Sunny Cars’ "all-round carefree package", all car hire-related taxes, charges and fees are already included in the hire price. These include, for example, airport charges, airport tax and local taxes on the car hire and the services included.

Additional costs may apply if you book optional extras such as a child seat, a sat-nav or a one-way hire. These costs are clearly shown at the time of booking and are paid on arrival to the local car hire partner.

In addition, certain destinations may be subject to statutory government charges, such as environmental levies or tourist taxes. Where such charges are known, they are clearly shown before the booking is made.

In some destinations, statutory charges are levied; these are set by public authorities or public bodies and are charged directly to travellers. If local regulations stipulate that such a charge must be paid exclusively on site, it cannot be included in the rent.

However, we make standard government charges clear and transparent at the time of booking. This way, you’ll know in good time what additional costs, if any, you may need to pay whilst you’re there.

Debit cards are generally not accepted – a note to this effect can be found at the top of your voucher. In some cases, certain partners accept debit cards, depending on the destination and provider. Detailed information can be found in the special rental conditions, which can be viewed during the booking process. Alternatively, we recommend using the cash deposit filter or our no deposit service.

Sunny Cars not only covers the standard comprehensive insurance deductible, but also reimburses damage to windows, roof, tyres, underbody, oil pan and clutch as standard (see section 6 of our General Rental Conditions). If, for example, a stone damages the windscreen or you suffer a flat tyre and repair costs arise, simply submit the invoice after your return and Sunny Cars will refund the full amount.

Our Customer Service team will be happy to answer any questions you may have about sand and ash damage coverage for rentals in Iceland. Please contact them directly on 089 / 82 99 33 900 or by email at info@sunnycars.de to clarify all the details.

Some rental companies have a counter directly at the airport, some offer a shuttle service and some offer a so-called representative service. You’ll find the rental company details and contact information on the voucher provided with your booking. There you will also find directions to the respective counter.

Rental companies have different opening hours. You will find information about the relevant opening hours on your voucher. In most cases, it is possible to pick up or return the car outside of opening hours, sometimes for a fee.

If it is already clear before the start of the trip that the main driver will not be able to be present at the handover, we recommend changing the booking accordingly and assigning another driver as the main driver. This is possible up to 24 hours before the start of the rental. Please contact us directly to do this. This change cannot be made on site – in this case, the vehicle would unfortunately not be handed over.

All planned drivers must be present at the time of pick-up to sign the rental agreement and present their original driving licence. Additional drivers can be added later at the station.

Please note: Only drivers who have signed the rental agreement and presented their original licence are covered by the All-round Carefree Package.

You can easily book this service at most locations. In certain regions, the local car rental partner applies a small surcharge, displayed on the car selection page before you complete your booking.

If you are unsure or would like additional information – for example, about availability or pick-up – please do not hesitate to call our customer service on 089 / 82 99 33 900. 

Usually, you may return your vehicle outside of opening hours. It is important that you agree with the local car rental partner where exactly the vehicle should be parked when you pick it up.

In many cases, a signposted parking space is available and the key is deposited in a so-called drop-off box. This ensures that the return process runs smoothly even outside of business hours. 

If you want to return the vehicle to a different location, you can select the one-way rental option during the booking process. The system will indicate during the booking process if the local rental car partner charges a surcharge for this; which then must be paid on site.

For certain routes – for example, cross-border or logistically complex one-way rentals – online booking is not possible. In these cases, Customer Service will assist you, check availability and make the reservation.

Your rental car is generally reserved for one hour after the agreed pick-up time. If you’re running late, simply contact the local partner—details are on your voucher. 

When travelling by plane, providing your flight number ensures the rental company is notified of delays and keeps your car ready for you. You can also add your flight number to your booking at a later stage.

A rental day consists of 24 hours. For example, if you pick up the vehicle at 10 a.m., the rental period ends at 10 a.m. on the return day. Exceeding this time automatically results in an additional daily rental charge. Please note that Sunny Cars protection only applies during the agreed rental period; beyond this, the All-round Carefree Package no longer applies.

If you extend your rental on site, the terms and insurance cover of the local rental partner apply. We therefore recommend allowing sufficient time for the return.

Generally, you pick up the vehicle with a full tank and return it with a full tank. The exact fuel policy for your booking is stated in the Specific Rental Conditions, which are sent with the voucher, among other things. In most cases, it is "return as picked up" – i.e. you return the vehicle with the same amount of fuel as when you picked it up.

In most locations, hotel delivery is available. Enter your accommodation details in the booking form, and if no restrictions apply, the local partner will deliver the vehicle to reception and collect it there upon return. An additional delivery fee applies, which is clearly displayed during the booking process and paid directly to the rental company. If the price is listed as "unknown", please contact our customer service on 089 / 82 99 33 900.

With Sunny Cars, you can book an "Express Pick-up". At the airport, this allows you to use a fast lane, receive preferential service, and save valuable holiday time—especially at busy locations such as Palma de Mallorca or Olbia, where waiting times may exceed 90 minutes. With the fast lane, you’ll receive your car keys within minutes and can start your holiday right away.

Local rental car partners usually take forgotten items to the local lost property office. It is best to contact the local rental station (contact details on your voucher) or the local lost property office.

It's very simple! You will find the link on your voucher or in your booking confirmation. Please enter your details online at least 48 hours before the start of your rental. If you have an account, you can also check in directly there under "Current bookings".

When booking, select the "Contactless pick-up" filter and sign your online registration at least three days before pick-up date. At the airport, you can pick up your keys and rental agreement from the machine in less than a minute, pay the deposit by credit card and drive off without any personal contact. Returning the vehicle is also contactless via a key box; you only need to go to the counter if there is any damage. The service is currently available at selected airports in Curaçao and Spain. 

When booking, select the "Pick-up via smartphone" option: after landing, activate roaming, receive the rental agreement via text message, sign directly on your mobile phone and immediately see the registration number and parking space of your rental car. There is no deposit, and the key is in the car. You must register online at least 48 hours before collection; you will find the link on the voucher. 

The service is currently available at all airports in the Balearic and Canary Islands and must be booked at least five days before the start of the rental period. Extras such as additional drivers or child seats can also be added via your mobile phone.

In almost all cases, you will need to pay a deposit for the rental car, for which you will need a valid credit card (with PIN number) issued in the driver's name. In some destinations, we also offer a no-deposit service, which allows you to hire a car without a credit card.

The vehicle should be returned in the same condition as you received it. If the vehicle becomes very dirty during the rental period, we recommend that you clean the car before returning it (car wash, vacuuming). Otherwise, the rental company may charge a cleaning fee.

Yes, we recommend using Car Check both when picking up and returning your rental car.

Your data is transmitted in encrypted form and processed confidentially. Only you and the Sunny Cars systems have access to the transmitted content.

Car Check is a helpful addition to the documentation. Damage should nevertheless always be reported locally to the local car hire partner and noted in the handover report.

You can reach our team by telephone at +49 (0) 89 / 82 99 33 900 or by e-mail at info@sunnycars.de. You can find the current service times on our website.

Fines or warnings during the rental period must be paid by the driver. Sunny Cars does not reimburse these. The local rental company will inform you of any offences and charge an administration fee per incident. The original notice will be sent to you directly by the authorities.

Details on typical toll regulations depending on the country can be found in the specific rental conditions during the booking process. There you will find country-specific information, e.g. whether toll devices are already integrated in the vehicle or whether fees must be paid separately.

Sunny Cars offers rental cars with a standard term of up to 30 days. If you are planning to use the car for longer, this is also possible – in this case, simply contact our customer service on 089 / 82 99 33 900. Together we will find a solution that suits your travel plans.

Sunny Cars guarantees you the category you booked, not the individual model. The types shown on our website are only examples. If you would like a specific car, we will record this as a customer request, although availability cannot be guaranteed.

A guarantee is only available in destinations where we offer the optional "Guaranteed Model" service. For an additional fee, the exact vehicle you selected will be ready upon your arrival.

Electric vehicles are available at many of our partner locations. During booking, you can check availability at your chosen destination by selecting the "Electric vehicle" filter under "Vehicle type". Please note that availability may vary by location.

As we cannot guarantee vehicles with tow bars, it is unfortunately not possible to make a specific booking. If you have any questions, please do not hesitate to contact us via chat, by telephone on 089 / 82 99 33 900 or by email at info@sunnycars.de.

Sunny Cars does not offer vans for hire. If you need more storage space, a spacious multi-seater with up to 9 seats may be a good alternative. 

Sunny Cars does not offer camper vans for rent. We offer rental cars for your carefree holiday – alternatively, you can find out more about the optional extra "roof tent for rental cars". 

In most destinations, other people are also allowed to drive the car; often, an additional driver is even included in the price. Activate the "Additional driver" filter during your search to display suitable offers. If the service is not included, it can be added during the booking process for a fee. You can find out whether and what fees apply for one or more additional drivers on site directly during the booking process in the Specific Rental Conditions under "Information on vehicle pick-up and return".

Important: Each additional driver must appear at the counter, sign the rental agreement and present their original driving licence.

Unfortunately, we cannot make a general statement on this, as the regulations vary depending on the destination and rental car partner. If you need information about a specific destination, we will be happy to assist you personally. In addition to the chat, we are also available by telephone on 089 / 82 99 33 900 or by email at info@sunnycars.de.

As a rule, drivers must be at least 21 years old, and in some countries even 23 to 26 years old; exact limits depend on the destination and vehicle category. With the paid "young driver" service, the minimum age can be lowered with the consent of the rental company.

Some destinations also set a maximum age, which can be raised for a fee if necessary. All information on this is displayed during the online booking process, if you have any questions, please contact our customer service team (089 / 82 99 33 900) or your trusted travel agency.

Yes, in many countries you are allowed to cross the border with your rental car. However, in some countries it may be necessary to obtain special permission from the rental company. In some countries, a surcharge is also levied for crossing the border with a rental car, which must be paid locally.

Please indicate that you will be crossing the border when you make your booking, whether at a travel agency or on our website. The costs for crossing the border, if any, will then be displayed in the same step. Alternatively, you can also contact our customer service on 089 / 82 99 33 900.

We recommend that you indicate your intention to cross the border in good time to ensure smooth processing. 

Yes, absolutely! It is best to register the border crossing in advance, ideally when booking the rental car. If you book online, first select your vehicle and then specify the countries you wish to travel to; the system will check in real time whether the border crossing is permitted.

If you make your reservation by telephone or at a travel agency, inform your advisor of your itinerary so that they can obtain approval from the rental company. Without prior notification, border crossings may be refused or subject to additional charges.

Ferry travel is permitted with many rental companies, but it must be requested in advance to ensure full coverage. Please let us know your booking number after booking by calling 089 / 82 99 33 900 or sending an email to info@sunnycars.de and provide us with the relevant rental details (period, pick-up and drop-off location, desired vehicle category). We will check this for you immediately. 

If the rental company has restrictions on certain vehicles for roads or border crossings, you will find this information in the specific rental conditions in the vehicle selection.

Sunny Cars does not have its own vehicle fleet, but works with carefully selected local car rental partners worldwide. As the vehicle is provided by one of our partners, it is not possible to make a general statement about its age. However, you will always receive a vehicle that has been checked for road safety and is in perfect technical condition.

If you specifically want a new car, simply select the "New Vehicle" service when booking (subject to availability). You will then receive a rental vehicle that is no more than one year old or has a maximum mileage of 25.000 km.

A rental day always equals 24 hours. The time you pick up the car also determines the latest return time on the final day of the rental period. For example: if you collect the vehicle on 1 July at 1:30 p.m., the booking ends on 7 July at 1:30 p.m. If you return the vehicle later, the rental company will automatically charge an additional rental day for each 24-hour period—or part thereof. This condition is clearly stated in the rental agreement.

Your account only lists bookings made after registration; unfortunately, older bookings cannot be imported retrospectively. If you have already logged in and the new booking still does not appear, simply send an email to marketing@sunnycars.de so that we can check and fix the problem immediately.

If you wish to permanently delete your account, please contact us at marketing@sunnycars.de. We will be happy to do this for you in accordance with current data protection guidelines.
