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

I bought my first 65 Barracuda off the back row of our local Slowsmobile dealership in 1975, for $25. Battery was dead, so they swapped a good one in for me and I drove it home! In 1985, I bought a rust free 70 Challenger R/T roller for $75. It was a 383 4 spd car with factory air. FK5 with white interior. I had to sell it to be able to keep my house in 1989 when the ex wife left. :rolleyes: I put it in Hemmings Motor News for $3500, and it went to Switzerland. The dude who bought it flew over here, junked out a C body and put a 383 and a 727 in it. He had to have it operable before he could get it into Switzerland. I saw pics of it on Moparts at a car show in Europe years later!
