That's a great idea.
There's a place about 2 hours from me that has a LOT of vintage Mopars.
The owner is a pontiac guy and doesn't like Mopar guys. (I kind of understand since some of us are nerdy/fussy)
Anywhoooo- if you even start to say anything negative about gm while he's boasting their accolades (or even defend Mopar including with facts), or if you try to haggle on Mopar parts based on condition or an initially high asking price, the price goes up. He's threatened several times to crush all his Mopars, and only the Mopars. I've seen him tell people drop the part they just pulled if they point out damage or rust they hadn't seen prior to the pull, and then refuse to sell it to them, even at the initial price.
He's quite OK to throw that part in the scrap pile and get next to zero rather than take $125 for it instead of the $150 initially quoted.
I've also seen him stomp on Mopar parts to intentionally ruin them.
He's a pretty big dick, but has a LOT of Mopars with good parts.
