A friend of mine, 6 years old, changed the right back door to a 4S shop because of scraping, and the cost was more than 3,000 yuan. In my sixth year, I went to the 4S shop to change a rear bumper and the adjacent left rear iron plate for plastic painting, which cost more than RMB 1700. You drive to the 4S shop to ask, the most accurate! If you are not the owner, you can pay the advance payment and ask for a receipt. After the repair, you can check the maintenance documents, and return more and make up less.
