If you have bought from the dealership before and/or trust them, then bring
it back to them and let them fix it. If you have no history with them or
don't trust them, then bring it to a body shop and have them make up a list
of stuff that is wrong with it. There may be a lot more issues than you
see. If the paintjob is poorly done, as it appears to be, it will fade
differently than the rest of the truck and lower your resale value. By
then, though, you'll be way to late to have the dealer make it right. Don't
be shy to submit the receipt for the estimate to the dealer, either. Also
have the inspector take a guess on whether or not the truck really has 52
miles on it. Be nice, of course, but if they balk, let them know you aren't
going to be happy until you get what you paid for.

My father-in-law bought a Silverado that upon further inspection had been
Seriously damaged. The wind whistling through the door was a dead giveaway.
Grease fittings on the front end, too. OEM parts don't have them, but the
OEM replacement parts often do. Dealer wasn't very cooperative, but after
taking it up the chain and a lot of hassle, they gave him another truck.
