Picking up and dropping off the car at Frankfurt Airport is very convenient. There's a counter in the arrival hall where you can complete payment and then go to the underground parking level 1 to get the car. Returning the car was a bit tricky, however. The navigation led us to the lower levels (B2 and B3) of the parking lot. After driving around and exiting, we asked the security at the exit and found out that the entrance to the rental car parking area on B1 is near the parking exit via a small ramp. It would be great if the navigation could direct us to that ramp directly. When returning the car, three people inspected it thoroughly, showcasing German meticulousness. In contrast, in France, a single person glanced at it and said it was okay.

I booked a Volkswagen but ended up with an Opel after some hassle. The car's built-in GPS was very useful. Germany is really great for road trips; driving at 180 km/h felt effortless.

The staff at Dusseldorf airport were very friendly and provided clear directions to the car pickup area. We got an Audi A3, which was in excellent condition with powerful acceleration. The gas station nearby was very convenient.

The car ended up costing me more than expected because they gave me a vehicle that had just under a half a tank. I complained because I know how hard it is to bring back a car with less than a full tank. I ended up filling up the vehicle and giving it back with 30% more gas than I received it. This is BS and I will never do that again, if Enterprise wont give me a car with a full tank I will not rent a car from them again.
