Generally speaking, a lot of younger ppl have little knowledge or even care about the prominence.
However, cars of prominence are losing value do to the owners passing etc.
I think we are hitting the high mark in car valuations... & I do believe cars will start losing value as the younger gens don't care so much about provenance.
I used to care, but have come to realize that a nice "tribute" GTO (read that as a tempest with all the GTO parts) is probably more enjoyable anyway. Just like these fantastic plastic cars, all the "performance" and "looks", none of the financial drawbacks WHEN you drive it... and it should be driven. >>and I prefer the way Stan, Carlos, Lane, et. al drive them. Someday mine will be out there too. (It may not even be painted first... can anybody say gelcoat patina )
