I arrived at the Global Drive rental office at 7:30 AM. There were two staff members present; one was assisting a customer while the other was doing nothing. I waited in the queue for about 20 minutes before the idle staff member attended to me.

Couldn't rent a car, they didn't recognize the international driver's license from the rental company! It was a disaster.

Not bad, got a free car upgrade, the car was quite new. The insurance was a bit expensive, $21 per day for full coverage, but it was more convenient than third-party options.

The store is located in Terminal 2. After getting off the plane, follow the signs within the airport from Terminal 1 to Terminal 2. All car rental companies are on the same floor. It is very easy to find, right next to the orange-colored SIXT. The staff at the counter were very meticulous, friendly, and extremely patient, repeatedly explaining to us since our English isn't very good. We didn't get the original model booked, but instead received a Ford Focus. When we checked it in the parking lot downstairs, we realized it was a new car with only 11 kilometers on it. The car's condition was excellent, and both pickup and return were very convenient. This German local car rental company is also much cheaper compared to global chains. We'll definitely choose it again if we come to Germany for a self-drive trip!

The Mercedes Viano we originally requested was swapped for a Volkswagen Multivan. It drives like a bus, incredibly noisy and has horrible sound insulation! It's extremely uncomfortable to sit in. The front layout is like a truck with a two-seater next to the driver's seat, and the rear seats cannot be adjusted. There's no storage space at all, and we couldn’t even figure out where to put a cup of water. They claimed it was an upgrade, which is ridiculous! I will never use this rental company again. We spent over 10,000 on this trip and were expecting the comfort of a Mercedes, but ended up with nothing! Terrible!
