Look,1rst of all dealers are the most cheating guys you can ever meet.The only reason they don't wanna to fix the problem is because luxury cars are more expesive to maintain & service.The dealer would have to put out a considerable amount of $$$$$ to have that hood done & because it was a good deal for you they asume you'll pay from your pocket any other expenses the car might need to.Of course them can find people to deal with it,but aren't willing to cut their profits by selling you the car at a good price & beside that have to fix the paint issue.There's a lot a of good shops that you can inquire estimations from.Just take your time & have some research done before your deside what to do. I think that if the car have a comun colour it's easy to deal with than an car with a particular colour such as a rainbow.
