The staff of this car rental company are very reliable. When picking up the car at Munich Airport, they explained the details very clearly.

I arrived at Munich Airport before 6 AM. After exiting customs, I couldn't find the Caro car rental. I called the contact number but no one answered. Eventually, I asked at the information desk and got a phone, which is how I found the person picking me up. Everything else was very satisfactory.

The car provided by Caro exceeded expectations with no additional fees. The staff was excellent, answering every question we had with detailed and serious attitudes. However, one car in our group mistakenly used gasoline instead of diesel due to a lack of knowledge, disrupting our trip and incurring high repair costs, which became a major issue for our travel. Upon returning, I carefully read the rental order email and noticed a mention of this issue in the pickup instructions. Honestly, we never expected a small car to use diesel before going to Germany. Years of driving in our home country made us think all small cars use gasoline. If our friends hadn't made this mistake, I wouldn't have known whether we would have made the same error on our first refuel. The thought still worries me! It would be great if the rental staff could spend a minute to show us the fuel type by opening the fuel cap, preventing such mistakes. Therefore, I strongly suggest including a note about fuel type during car handovers, especially in international rentals!

We initially booked a Mercedes C-Class, but they upgraded us to an E-Class. Not bad! The car is very new, with just over 10,000 kilometers.
