I do think they have an inpact on our older cars but as stated above as we age and drop off there are not as many interested in them. People are drawn to what was hot and affordable when they were teens. My dod was a 50's car guy because that was what was hot when he was a teen. I am drawn more toward the 60-70s car for the same reason. At one time model T's were bringing in high dollar, not so much anymore.
