The list is BS.
I had a 1973 AMC Gremlin X. 304 V8. Lots of power. That car was fast.
I bought it for just under $ 3,000. I sold 15 years later and got I thing around $ 1,500. I also had other AMC car and they treated me good.
When you are in your teens, who cares what the car looks like, you just wanted any car. Not like the kids today that want a brand new $ 30,000 car with no concept about maintenance and insurace costs.
Besides, those cars in the 70's, were made to be serviced by yourself and not take them to the dealers to be ripped off.
