In 1974 I bought a '72 Chevelle body shell to use to reskin a '69 Chevelle stock car. The '72 had been totaled and the front end sheet metal, engine, and transmission were gone. The interior was intact.
After I'd loaded it on my trailer, I stopped for gas on the way out of town. (Omaha). Before I left the gas station, I'd sold the white vinyl bucket seats for more than I paid for the whole car.
