The car crashed. Is the back wall partially cut or repaired? Can this be repaired by sheet metal welding without cutting? Is repairing or cutting less harmful to the car?
If the sheet metal is difficult to process in this part, the general repair unit should want you to cut and weld. Although the overall structure of the car should reduce safety, it is relatively easy to control! The price is not too expensive! The whole structure after sheet metal is not good either, as long as you pay attention to driving in the future, you will be fine! See how you choose.
