Best deal you’ve ever made on old cars

In 1976, I bought a 65 Barracuda, 273 automatic for $25. Found it on the back row of the Oldsmobile dealership. Put a battery in it and drove it home. In the mid 80's, I bought a 70 Challenger R/T roller for $75. 383 4 spd car with AC. FK5 with white interior. I sold it in 79 for $3500 to a dude from Switzerland.
