I am going to buy a car. I watched the car test drive in a 4s shop these two days and received a new car mortgage message from the Traffic Management Bureau. What happened?

Check the exterior and interior of the vehicle, and check the places where the shoes are easy to wear for traces. The final means is to check whether there are pits or small on the tire surface except the tread pattern. Look carefully between the patterns, that is, always go on the road to see if the brake disc is flat or wavy. You can compare the cars in the store. The more flattering you are, the less you cross the road. You would rather not buy a new car than make do with it! ! ! I hope it helps you.
