This story may not be quite what the op intended, but here goes.
Back in around 2015 or 2016, I had a coworker who had a couple of fox body Mustangs and a bunch of parts he wanted to get rid of. He had asked me if I was interested on a couple of occasions and I told him I would like to see the cars first.
He said that the cars were in his dad's backyard and that he had to let his dad know before I could go see them. Finally after about 2 months he told me to come by that weekend and I would be able to check everything out.
When I got there, he had the 2 Mustangs, both 1983 GLX models, both t top cars, basically complete, one had a 302 that he thought had a bad cam, plus a 351w on a stand, a freshly rebuilt set of aftermarket sbf heads, a pile of miscellaneous parts, wheels, tires, etc, all for $500.00. Then his dad came out and said he would sell me his 1991 GMC 3/4 2wd pickup for another $400.00. I drove the truck home with a load of parts and had a buddy come down with a deck truck to haul the cars to my house.
2 hours later, my buddy phones and says his son wants to buy the truck so I sold it for $900.00, now I have 2 cars plus a ton of parts free! Over the next few months or so I got the 302 running perfectly, firing order was wrong, and sold off pretty much everything, made about $5k profit.
