You'd better find a second-hand car dealer who knows the ropes. The used car I bought last year, Suzuki Tianyu Shang Yue, was seen by a friend of mine who is a used car. Suzuki is really a good car. Although the sales volume is not good, the car is really genuine leather. As long as there are no accidents and major repairs, there will be no problem. This car can't break down.
Buy used cars, especially older ones. I suggest buying a Japanese car.
