From hear you need to determine who painted the car, should be fairly easy to determine if it has. Very few painters will remove all the trim and weathersrip so look closely there, Lift the rubber a little at the door window area. If the car was painted prior to delivery it could have been transportation damage or even a warranty repair, either are not uncommon. As a painter by trade when I was younger, never ever think that a man with a $300 spray gun can provide what the factory puts on the car. It just can't be done. Good luck and hope the entire car doen't have to be done.
