The one thing I find ironic about "Built Not Bought" is that NO ONE is making EVERY single piece for their car. No one is mixing paint colors out of nothing, skinning animals for their hides for their interior, shaping panels from steel sheets, etc etc. Everyone buys something that goes onto their cars. Be proud that you have the skill and time to do what you can to your car and enjoy the hobby with other like minded enthusiasts.
Maybe we should all hate GM, Ford & Mopar for BUILDING all of these cars that we have BOUGHT.
