That concern pops up now and again on all car forums and it's completely overblown. A good paint job is more than good enough and is sometimes superior to the factory paint. I realize you've had a difficult time of it and I'm sympathetic to your complaint in chief that a purchaser of a $132k car should not have to deal with problems like this, but don't make yourself crazy worrying about the impact on resale value if the car ends up being put under a microscope by a prospective purchaser. 9 out of 10 purchasers won't do anything like that (especially commercial purchasers) and it is a fact that most pre-owned cars (and a significant number of new cars) have had some minor cosmetic repair work that, if done properly, should not detract from value.
