The old man was very helpful, upgraded us to a diesel Volvo T6! He patiently explained everything.

They provided a nearly new Mercedes with only a few thousand kilometers on it. The deposit wasn’t as high as mentioned in many guides, only a 800-euro pre-authorization. Both the pick-up and return procedures were very simple, likely because cars are much cheaper in Germany. They didn't even inspect for damages thoroughly during the return.

We had a car accident during our rental period, and because the car was damaged, we couldn't continue our journey. Caro sent a new car from Germany to a rural area in France, 1000 kilometers away, within a day. Their dedication is commendable. We were deeply moved and highly appreciate Caro's people-centric approach. We also recognize that all the cars provided by this rental company are new Benz models, which is excellent!!! The only downside is that the airport does not have a fixed pickup point, making it harder to find.

The car was relatively new and they awaited our arrival promptly.

After arriving in Munich, we called CARO customer service from the Starbucks near customs. The customer service asked for our exact location at the airport and said an employee would pick us up since the office is a bit far from Munich Airport. We waited about 20 minutes for them to arrive. We booked a manual diesel Passat wagon or similar, but we got a Mercedes C180 wagon instead, likely because of the emissions scandal with VW. The car was very new, with less than 10,000 kilometers, and we were very satisfied. However, it was switched to a petrol car that runs on 95 octane, which made the fuel more expensive. The staff was very thorough during pickup, carefully noting all existing scratches on the car. The in-car navigation system was very convenient with English voice prompts, so no need to change settings (unlike our previous rental in France where the system was in French and we couldn't change it to English). The QEEQ navigation was slow in finding satellites, and some addresses were not found, so we relied on the car's GPS and Google Maps. During drop-off, we faced some issues because we aimed to reach the airport early for tax refund and shopping. We called the day before to arrange a 7 am drop-off, but the gas station near the office opened at 7 am. The prices were higher than the market rate, but we didn't need much fuel. After refueling, we returned to the office, but no one was there. We called again and were told someone would arrive in 7 minutes, but it took nearly half an hour for an employee to return from picking up another customer at the airport. He was short-staffed as his colleague didn't show up, so he called a friend to help. The return process was finished around 8 am, and he drove us to the airport in the rental car, unlike the shuttle bus used during pickup. If you are catching an early flight, allow extra time. Initially, we set the pickup time as 6:30 am and the drop-off at 1:30 pm, but the actual pickup was at 7:00 am, and we arrived for drop-off at 7:00 am but had to wait for service. We effectively lost a day of rental, but we were in a rush and didn't argue as they didn't even use a computer for the return process, relying on the printed documents from pickup.
