I think we're mainly talking about reasonably priced cars that people bought, used and traded without any particular care or regard.
This is the normal lifecycle for most volume models. You see a lot of them up to the fifteen years or so point after which they become thin on the ground.
A few may become cult cars, as is the case with the Vanagon somebody mentioned above. That struck a chord because we had one. The Vanagon sold in about half the volume of the Corvette in the US when it was available and cost about as much. For that coin, you got a superb handling SWB van with enormous interior volume that was also quite slow. The Vanagon has since become a cult item as the last rear engined VW and even an average running and driving example will run you a fair amount of coin.
