used is used.. and it sucks many monkey butts.
i bought a brand new brz limited in january. about a month ago, a chick decided to not pay attention to her stop sign and blew through it right in front of me. car was totaled, her insurance gave me $6k less because now it's legally a used car. i turned around and bought another new brz limited, because i was very happy with the car. but now i'm out $6k. because another driver can't drive.
legally, a non-titled vehicle is always considered new, a titled vehicle is considered used. that's it, it really is that black and white. they might reduce the price because of mileage if it was a loaner or a demo, but that's it.
if they had caught the paint imperfections/damage before you bought the car, they would have sent the car off to be repainted anyways, and you wouldn't have even known the car had repainted parts.. that is how cars are handled by dealers.
would you knowingly buy a car that was borrowed from a dealer for an auto show, where everyone sat in it, played with it, and it got wiped down with the same dirty rag for hours on end? most people wouldn't. but those cars are all sold later, because they go back to the dealership they were borrowed from, and the dealer reconditions them-- they replace the seats the kids tore up, they buff the paint to get rid of the scratches, and then they put it on the showroom, and sell it, most of the time with no one knowing any better about where the car had been.
also, i don't believe you fully understand how carfax works, and i also believe you have been lead like many others to believe that carfax is the end-all-be-all in car history reports. that is not the case at all. trust it carefully, and never fully.

i would need to research it more, but i don't believe that something like paint repair would show up on a carfax report, as they mostly look for damage that usually involves an incident with a filed police report. as in that link, there is also absolutely no guarantee that even if it should be on that report, that it will be on the report...
