As for the question you asked, because you don't know the pre-maintenance of the vehicle, you'd better go to the store for a comprehensive inspection after purchase, and check all the oil, timing system and braking system. If a problem is detected and repaired in the store, no detection fee will be charged. If the problem is not fixed after the inspection, the store will charge an inspection fee of 200~500 yuan, which is determined by the store itself and varies from store to store. You can add fog lights to this car. I hope my answer is helpful to you.
