Overall, it was okay. The car was new, having just over 10,000 kilometers on it. The vehicle was in good condition. However, the customer service insisted on adding insurance when we picked up the car. We initially chose the secondary insurance, but they said German roads are narrow and that even if we didn't hit someone, others might hit us. We had to add an extra €198 for insurance. They also recommended more expensive cars like BMW, even though we repeatedly declined. This was quite uncomfortable. The car pickup process took almost two hours, likely because the rental company is small. It might be considered big in Germany. Returning the car took a long time as well since it was hard to find the return location. Most major rental companies are at the train station, but this company's prices were reasonable. In the US, we never encounter such issues. After landing, rental companies are inside the airport, and you can get the car quickly. Germany's process is slightly more complicated. However, returning the car was quick. After handing over the keys, they checked the car inside and out, including the fuel. It was a fast process. Thumbs up for that.

Overcharged

Long waiting time in line, they changed the car model without permission, giving me a 1.6 Jeep Renegade (which starts at 110,000 RMB in China). I had reserved a BMW X1, but they claimed both cars are in the same category. The 1.6-liter engine's acceleration was terrible, and the driving experience was very poor. Complaints were useless; they said if I wanted to change the car, I had to pay more, and they kept pushing insurance. This rental company is very small, has few vehicles, and the car we got wasn't even German-plated; it had Slovakian plates. Be cautious when choosing a rental company. Don't do what I did, choosing a cheap option and regretting it later. Beware of foreign scams.

The queue was very slow, and the car I got had issues.

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!
