You're probably right. Don't remember who said it, but it was mentioned that Toyo Cruiser's didn't increase in value for quite some time. OTOH, I can't remember seeing those priced anywhere near what Camaros, Corvette's, and Mustangs sell for -- when really valueable.
Correct me if I'm wrong
Even then, it's a really old car (that takes thousands to restore) and/or it's a special car/model -- to get $50k, $100k, or more. The Cobra 500 models would be a good example.
