The car we picked up had a dented door and issues with the headlights and taillights that wouldn't turn off on the first day, but somehow fixed themselves by the second day. We picked up the car at Frankfurt Airport, and even though the paperwork noted existing scratches, the staff at the Munich Airport return location was shocked and called the Frankfurt office to verify the severity of the damage before believing it wasn't caused by us. Another group of Chinese tourists who rented an SUV found a tire pressure warning just after leaving and had to come back; they eventually had to go to a repair shop as there were no spare cars. If such a delay happened to us, I’d be extremely upset. Due to these issues, I probably won't rent from this company again.

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

The cars from Caro are very new. I booked a Mercedes C-Class station wagon, but they gave me a brand new Mercedes E-Class station wagon upon arrival. An upgrade without additional cost, fantastic! The car was diesel, very fuel-efficient, and powerful, easily reaching 220 km/h on the highway when there was little traffic. The pick-up process was very simple. I had reserved to pick-up and drop-off at Frankfurt Airport. Upon arriving in Frankfurt, I contacted the car rental company, and a friendly gentleman driving a Caro-branded van met me at the airport's Exit 5, holding an A4 paper with my name on it. He drove me and my luggage to the rental office, checked my driver's license and notarized documents, swiped the deposit, got my signature, and I was all set to go. It was a pleasant start to my road trip! When returning the car a day earlier than planned, I filled up the tank and arrived at the return point at 9 PM. The company's staff had left for the day, so I contacted Caro, and they told me to drop the car keys in the mailbox for self-service return. Not feeling assured, I drove the car back to the hotel and returned it the next morning. On the way, I encountered the Caro van and tailed it to the return point. The gentleman drove very skillfully! After some back-and-forth, the fuel gauge dropped slightly. I explained the situation to the gentleman, and he waived the extra charge with a wave of his hand. Amazing service! It was a smooth and pleasant car rental experience!

Although it's not a big company, their service is very attentive.

Good value for money, vehicles are relatively new
