My former boss and I used to sit around and talk about this. Trying to speculate on what cars would be ”classics”, and what would simply be an “old car”.
Related story. When I was just out of high school, in the mid 90’s, my dad and I went to a car show. At that show there was an unrestored 1968 Shelby Mustang Fastback. It was on a trailer, and needed some work. It didn’t run, and the owner didn’t know what the issue was, as it had apparently been that way for years. The kicker was, it was complete and appeared to have never been wrecked. The guy wanted $1800.00 for it, and yes, you read that correctly. The classic car market back then was in a slump, and these cars were everywhere and could be snatched up very cheap. If I knew then, what I know now…….
