Frankfurt-Hallstatt-Salzburg-Regensburg

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.

Unjustified charges, poor service attitude.

I rented a station wagon, but they only gave me a Ford Focus hatchback (see picture, it's not a station wagon and very small). They insisted this was the station wagon, which was completely unusable for four people. In the end, I had to pay to upgrade. This rental company is quite deceitful.

Completely dishonest. Confirmed an automatic MPV at booking, but at the airport, they said they didn't have one, so I had to take a van. There was no damage when returning the car, confirmed in person, but they still forcibly charged 500 euros on my credit card, refunded only after multiple complaints. When picking up the car, I noticed the rear wiper was broken, and it was clearly noted in the contract, but they still charged over 100 euros, claiming it was a repair fee. They repeatedly confirmed it was a gasoline car, but it was actually a diesel, almost damaging the engine.

Very poor service from the rental location. They exploited the language barrier to add hidden charges, increasing the total cost deceptively. They even swapped my car for a small Opel SUV, which was totally unexpected.
