Goldcar, Firefly, Centauro & Co - The tricks of the car hire companies
There are countless negative reviews on the Internet from vacationers about car rental companies such as Goldcar, Firefly or Centauro. The European Consumer Center (ECC) Germany also regularly receives complaints about questionable business practices of car rental companies. Despite official sanctions, some companies continue to use questionable methods to deceive customers.
Find out what tricks car rental companies like to use and how you can protect yourself.

Treacherous car rental bookings via price comparison sites
When searching on price comparison sites (e.g. billiger-mietwagen.de or Check24), you will usually come across car rental brokers (e.g. Auto Europe, Rentalcars, CarTrawler or HolidayCars). Car rental companies offer their vehicles there at low prices in order to appear as high as possible in the search results. When picking up the car at the counter, the car rental company tries to sell expensive additional products to the traveler. This is one of the most common complaints from consumers who have booked their car hire abroad through a comparison site.
In addition, with three different companies involved (comparison site, broker and car rental company), it is difficult to find the right person to contact if there are problems with the rental car. Find out more here.
Common consumer complaints about car rental
Imposition of additional insurance
Comprehensive insurance with no deductible is often purchased through a car rental broker. At the rental location, however, customers are told that they need additional insurance in order to rent the vehicle. Those who refuse risk long discussions or even a refusal to hand over the vehicle.
Many vacationers then give in - for fear of being left without a vehicle and losing the deposit they have already paid to the broker.
Problems with credit cards
Credit cards used to pay the deposit are often refused by car rental companies, either because of alleged technical problems or insufficient funds. Customers are then offered additional insurance for a fee as the only alternative.
Debit cards (e.g. Visa or Mastercard) are often refused for no apparent reason.
Opaque contracts and hidden costs
Rental car customers repeatedly report non-transparent contracts and unexpected costs. For example, additional insurance is often added to the bill without consent. When inquiries are made, it is claimed that this is an alleged “deposit”.
In addition, employees often pressure customers to sign quickly, usually on documents that are only available in Spanish or another foreign language.
Another problem is that the signature is often made on an electronic device and customers do not receive copies of the signed documents, which makes it difficult to prove discrepancies later.
High fuel deposits
Consumers report high fuel deposits that are only refunded months later or not at all.
Damages charged after the fact
Holidaymakers report being charged for alleged scratches or dents after returning the vehicle.
Chargeable upgrades
Customers are offered an upgrade on collection because the vehicle they originally booked is said to be unavailable. It is suggested that the upgrade is free. Only later does the customer discover the high additional cost on the final invoice.
Trouble with Goldcar, especially in Spain
The car rental company Goldcar has already been fined several times for unfair business practices. Read more on the ECC Italy website.
Nevertheless, there are still complaints from consumers, especially from well-known Spanish holiday regions such as Palma de Mallorca.
What should you do if you have been wronged by a rental car company?
- Leave an online review. Negative reviews on Google, Trustpilot or the booking platform increase the pressure on companies to change their business practices.
- Contact the bank: If you have been unlawfully charged an insurance or fee via your credit card, you can often request a chargeback. Pointing out negative reviews or sanctions against the provider may convince your bank.
- Vehicle not handed over? If you have been refused the vehicle, for example because you have not taken out additional insurance, ask the car rental broker (if you booked through them) for a refund of the deposit. If they refuse, a chargeback through your bank may be a solution.
- Help from the European Consumer Centres Network(ECC-Net): In some cases we can get money back for you out of court. We also refer cases to enforcement bodies. Our help is free of charge.
- European Payment Order Procedure (EPO) or European Small Claims Procedure (ESCP): These procedures help you to enforce claims in court across borders. Check whether your legal expenses insurance will cover the costs or get support from a lawyer.
5 tips on how to protect yourself from rental car traps
- Read reviews: Look out for recurring patterns and use several independent review sites.
- Avoid price comparison sites: Rather book directly with local car rental companies that offer reservation without prepayment.
- Don't sign anything you don't understand: If the contract is unclear, ask for an explanation or use translation apps such as Google Lens to have the contract translated directly via photo.
- Complain: If you feel pressured and have no other choice, document everything and complain immediately by email. This way you will have proof later when you claim your money back.
- Document the return of the rental car: If possible, only return the vehicle in the presence of an employee and have a return protocol issued. Take photos and videos of the vehicle - both when you pick it up and when you return it.
