The car was in great condition, and the service was good. Although not located inside the terminal, they provide shuttle service.

The service was excellent, with someone specifically waiting at the pickup point. However, the car handover process was a bit lengthy, taking about an hour in total.

We rented a small manual Polo from Caro. Overall, the car was in good condition, especially during flat acceleration, though it lacked some power when driving uphill. The service attitude was very good.

There was no counter at the airport, we had to wait for the staff in the parking lot. They arrived late, and it took about 20 minutes to complete the paperwork. All charges were deducted from the credit card. We were a group of four with a lot of luggage, so we rented a mid-sized Passat, but they gave us a small Mercedes. The car didn't feel as spacious as the Passat, but considering it was an upgrade, we accepted it.

Overall satisfied, but returning the car was a nightmare! The reason is that when picking up the car in Frankfurt, it was confirmed that the car was to be returned at Frankfurt Airport (common sense would think it's at the terminal's lower level), but upon arrival at Terminals 1 and 2, we couldn't find the CARO company office (other rental company offices were all there). Desperately asked locals for help and found out the CARO return office is in a nearby town. This was not clearly explained by the staff during pick-up!!!!
