I just bought a new car. When I got it home, i noticed 4 small scratches on one side that are a little deep and on the other side, there are 3 light scratches. The bumper and passenger side has some kind of yellow substance on it and the bumper has these weird speckles. The dealer has offered to fix everything for free. Should I have the stuff fixed? Is it possible the dealer will do a poor job and the car will look worse later on? Should I try to return the car? Will the clear coat come off with the speckles and light scratches?
