Booked a Mercedes, ended up with a Ford. There were at least two similar Mercedes parked nearby. When I asked customer service, they said it's the same grade and refused to change.

Great service!

This was the worst car rental experience I've had in many years. They gave us a car that already had scratches. Thankfully, we had full insurance and took photos when we picked up the car. We returned the car in Salzburg, and the rental company staff there asked for a damage report from when we rented the car. No one had given us or reminded us to take such a report earlier, but they said it was fine since we had full insurance and we wouldn't need to pay extra. In the end, we found out they charged us an additional 140 euros, and we have no idea what for. We contacted the rental car service to inquire. It's been over a week now, and we still haven't received a response. Very dissatisfied.

The two staff members at Hertz Munich Airport were very nice. We encountered some issues when picking up the car, but after four to five hours of effort, they eventually managed to rent us a car. Returning the car in Frankfurt was very convenient; the staff just drove the car to check the mileage, and that was it. They didn't inspect the exterior, possibly because we had purchased the comprehensive insurance. We had reserved a BMW X3 but were given a Volvo wagon instead. The car was a diesel model, very new, with many features and a built-in German navigation system that was quite useful during our trip.

Renting a car at the airport is very convenient, and the staff have a good attitude.
