Caro is not at the airport, you have to wait for their staff at the McDonald's next to T2. There's a gas station next to their office, which is very convenient. The Germans are very meticulous in their work. We rented two cars, and they handled the paperwork for one car before starting on the other, so we waited a long time, but the instructions were very thorough. We reserved a C5, but got a brand new Opel with only 4100 km on it, featuring auto start-stop and lane assist. These features are very important for driving in Germany. The car also has radar systems at the front and back. The condition and performance of the car were excellent, and it had a 6-speed manual transmission.
