Someone scratched the corner of my bumper while they were parking next to my car. The scratch was quite a big one and is visible from a distance. The paint has come off entirely showing a ugly black patch. The mechanic says they need to paint the entire bumper at a cost of $200. However my bumper is not entirely immaculate. It has a insignificant scratch to the other side.The bumper also has a scratch free dent that I believe is by design.
Could you please suggest how should this be sorted? Thank you.
