I rented a car at Frankfurt Airport in Germany from Dollar Rent-a-Car, sharing an office with two other rental companies. There were few staff members, and the queue was very long, taking three hours to rent the car. We traveled through four countries: the Czech Republic, Austria, Switzerland, and Germany, and had to pay an extra 50 euros for crossing borders (this was not a highway toll but an additional fee charged by the rental company). This fee was not mentioned in the rental agreement.

The staff was very friendly and attentive. However, the car given to us, while having low mileage and being relatively new, had some issues during driving. The RPMs would spike unexpectedly even at speeds of 50 or 60 km/h, reaching 3 or 4, which made me hesitant to accelerate. Additionally, there was an extra charge for diesel cars, costing 5 euros per day, which wasn't very economical.

The car was new and in excellent condition! It was very comfortable to drive. The staff was professional and friendly. Communicating in English was not an issue.

Complete mess! This company is a scam and the worst I've ever encountered! They find every fault to prevent you from getting the car smoothly, forcing you to pay more, buy extra insurance, and even use deceptive tactics. The staff attitude is terrible! I heard about such cases in the US, but it's the same in Germany too. I can't imagine what it's like in other locations! I hope everyone avoids this company despite their seemingly low prices because there are more traps waiting...

1. The front of the car got scratched by some dry branches on the ground. It wasn't very serious and should just need some paint touch-up, but I was charged over 800 euros, which is too much.
