The popular models ( you have your own list ) will always bring the money. Certain cars have half way worked their way into a bit more money ... but now they are back where they were. Real 32 Fords Real 33/34 Fords 40 Fords ... Are on the TOP of my list. And as a general rule, prices reflect that. What we have seen ( IMHO ) is a rodders buys a so-so model ( less desirable generally ) for cheap money and then sinks a ton of work and $$$ into it. They then thinks it should be priced like the " desirable " one. He prices it that way ... but we all know it will sit and not sell at the big price . In the past 35 years I have owned 32 Fords ( henry Steel cars ) and 1940 Fords. I have NEVER lost $$$ on any of them. Good cars bring good money !!
