I'd rather have that little Barracuda over ANY Vette, regardless of the worth, but, then again, I'm a tad partial to the bodystyle.
As mentioned previously, 40k tops, depending on how solid she was underneath. 30-35K easy is what it was worth. If you were looking for an investment car, I believe that the Barracuda would have made a better one than the T/A, as I feel that the AARs and T/As have nearly reached their price ceiling, and will no longer increase in value dramatically, as have the other 70 and 71 E bodies. However, A body ragtops, ESPECIALLY the Big Block cars, I feel, will become the next High Dollar car (which means I better get myself a 69 ragtop soon), since they are also rare, and have plenty of muscle. So, I expect them, and other A bodies, to increase dramatically in value within the next 5 years, especially as the B and E bodies become further out of reach.
