What’s the best deal you’ve gotten on cars or parts

I picked up a excellent e-body wood steering wheel for $75, along with a b-body console that was all there, but needed cleaning/paint for $100. The wheel brought $375, and the console when renewed brought $750. I also took this air cleaner off this Ford cobra when I sold the car, cleaned it up, painted it and sold it for $1400. I also bought a rebuilt 440 about 7/8 years ago with 2x4's on a tunnel ram intake for $1600. Sold the intake and carbs for $400 so the 440 was a $1200 purchase. It turned out to be a dud I found, after I installed it in my '63 Polara.
I have purchase many cars over the years and can't tell you how many times people have include so many parts with the sale. I don't know if they wanted to remove reminders of the car they sold, or get stuff out of their garage. It has been like a cherry on top, and recoup some cash. I have to admit I don't include any-thing when I sell a car, sorry.:) (Need to find picture of that 440).
