I originally chose a RAV4, thinking Japanese cars are more fuel-efficient. When I checked in at the check-in counter, the guy said the only comparable models were Mazda and Chevrolet, so I chose the Chevrolet because it was bigger. From check-in at the counter to picking up the car and taking photos for record, the entire process was quite convenient, and the return was also quick. The car was in great condition, clean inside and out. Ctrip also offers a car return document, which was very reassuring. I'll definitely choose it again next time.
