I get alot of "wow , what a really nice car....but I would have done X instead".... big block rather than small block, auto rather than manual, blue rather than red....blah blah blah.....good for you....now get the F out of here......
Dont even sweat it. Its like trying to be the bully at school.....its usually a pathetic way to make themselves feel better about their cars or boost their ego, when in fact both of them suck
In my experience, the "paint and body" crowd is the worst. Thye all nit pick and attack each others work. Somehow each one of them feels that they are the only one on earth than can paint a car "right". Any other way is crap and they wont hold back telling their friend as they stand next to your car.
