a body value

I'm optimistic that my 68 Barracuda 340 Formula S factory A/C car will keep appreciating. Even though the original motor & tranny was lost long ago before I got the car, I'm still thinking of some day trying to find a numbers correct 340 block and drop into it and keep my '70 block around as a spare. I haven't been a stickler for originality so far, I painted it a '95 Chrysler color instead of the original maroon. It's still maroon just with a little mica/pearl in it. I'll have to post some pictures of it someday soon. I should have it back on the road sometime in August after a 24 year vacation from DMV registration. NADA classic car says it's worth about $22,600-$43,400 going from average retail to high retail respectively. It all boils down to one thing, something is only worth as much as you can find somebody that is willing to buy it from you for.
