1969 Barracuda Value.....

When I picked up that 64 slant Savoy, I asked Joe Suchy what it would be worth as a roller with all body metal work done, primed, blocked, and pretty much ready to seal and topcoat. Joe is one of the early B body gurus and has been for decades. He said hard to put a value on them but between $5000 and $10,000 was his opinion.
I see such kind of car, done, with just a decent running BB bring around $18,000 to $20000 or so. (Sure someone can spend $10000 building a BB and trans too, but.) I also see them higher. I see MW clones done, bring $25000 to $35000. Clones, tribute cars. WE see real MW cars, done, bring silly $ also.
Point is the more $$$$ someone pays for any old car, the more he requires perfect work on a real car.
The difference between clones and real, is: 1. cost of a project and 2. cost of parts that make it real. It costs just about as much, in general, to do body/paint, build mechanicals, suspension, interior, etc. as a slant car or a hemi car.
Matching numbers on 69 up engines/trans, those cars are few and far between and always have been. Bogus cars are another subject.
