Clearly deceiving consumers. Initially said they would give us a Volkswagen, later I mentioned we booked a Mercedes, and then they just found a sedan version, not the wagon we booked. Our luggage almost didn't fit.

Waited 45 minutes in line to pick up the car.

I have rented cars in Germany twice. The first time I rented an Audi A4 estate, but since they didn't have it, they upgraded me to a Volvo XC60, which was okay. This time I booked a Mercedes E-class estate, and again, they didn't have it, so they upgraded me to a Volvo XC60. Initially, I was a bit upset, but I found the XC60's noise insulation to be much better than the E-class estate I rented in the UK, and it had more space. The interior quality is much lower, and the driving feel of the Mercedes is definitely a class above Volvo.

A big company is indeed different, the cars are very new and the service is good.

The company is very professional and truly deserving of being a world-class car rental company. It was easy to find following the instructions after leaving the airport. Since we crossed the border into Italy, they replaced the Mercedes with a 9-seater Ford. The only drawback was the requirement to purchase comprehensive insurance (originally insurance was included, but it might have been invalidated by crossing the border). The original 10-day rental was 641 euros, but it totaled 1099 euros in the end, which is a bit pricey.
