I do this very job for a living , albeit for car dealerships primarily , we do about 10 % of our business via retail customers as well and not random people in a parking lot . He messed up his sales approach badly . That being said , he probably would have fixed your bumper as stated . And unfortunately he ' s about right on the body shop cost to repair and how they ' d go about completing the job by replacement . He was shooting high at $ 400 $ 300 is our standard cost for basic repairs no cracks or major dents in the plastic . That ' s a strategy we ' ve developed from dealing with car salesman for a living , shoot high then come down a little so they feel like they ' re getting a deal . Honestly , you probably made the right call because he sounded a little off , but these services do exist in at least 20 states , that I ' m aware of , probably more . Search , mobile paint repair .
