Frankfurt-Bonn-Stuttgart-Munich-Heidelberg-Frankfurt

Very good

Firstly, the vehicle categorization is unreasonable. I rented a compact car but was given a Jeep. They told me it falls under the same category as a compact car. Driving a Jeep on the German highway is slow and fuel-inefficient, with a consumption of 17 liters per 100 kilometers, and I had to stay in the slow lane with trucks! Also, I was driving alone and didn't need such a large vehicle, which was also difficult to park in the city! Additionally, Thrifty provided a Hertz car. After picking it up in Frankfurt and driving to my company in a smaller city, I couldn't exchange it at a local Hertz office. After a week of inconvenience, I had to drive over 100 kilometers back to Frankfurt to switch the car! Lastly, there was a price difference between the rental company and the price on Zuzuche, which is completely unacceptable to me!

Good.

I reserved a BMW 3 Series but was given a BMW 5 Series Touring. It's a diesel hybrid, comes with navigation, and can display the speed limit on the dashboard with the vehicle's LIM speed limit function, making it very convenient to avoid speeding. The upgrade was great...

The service at the Frankfurt Airport branch in Germany was just average. When picking up the car, a hold was placed for a full tank of fuel. I booked a Benz C but received a Jaguar X20d diesel car instead. The car felt a bit small, especially the trunk, but the diesel engine did reduce travel costs. I was a bit late returning the car, having mistakenly entered the underground parking and returning it just over ten minutes late. I was charged an extra day because I picked up the car slightly early, despite confirming with the staff that I could wait until 9 AM to collect it. They agreed, but still charged according to the scheduled time. During the pickup, I noticed minor paint scratches and discussed them with the staff, so the actual pickup time was around 9:30 AM, but I didn't ask them to reprint the pickup contract. In the end, I had to negotiate with the manager at the branch, explaining the situation, and they ended up charging me a little under 15 Euros. Typical Germans, very rigid! While they weren't wrong and had a strong sense of contract, their service awareness was practically non-existent!
