When getting a major $$ deal on a car

I hate flippers.
A few years ago i saw a very well known person in the mopar community, browbeat, harrange and generally whine about a rare part he wanted. The price asked was very fair, but this person hung around and hung around until the seller lowered his price, just to get rid of him


Minutes later, the very same part (very rare item, unquestionably the same item) was in well known mopar persons space, marked triple what the original owner was asking.
Okay, its worth more money. Then why did you have to beat the guy down some more, you prick!?! Pay him a fair price.
I have refused to buy anything from that prick to this day.
I had something like that happen to me years ago. A guy I knew who was a flipper was after a part I had, I had a couple of them, but he was insistent that he wanted the best one I had, which I was going to use on my own car, claimed that he needed it to close a sale on one of his cars, blah blah blah, pestered me for half a day about it until I got tired of him and let him have it cheap. A week later he was selling the same damn part for double what I sold it for.
