Yes, it's fun to drive, and to take to car events. The biggest kick usually comes when people find out it has not been restored. I get a lot of compliments like "hey, nice job on the restoration". Then jaws drop when I tell em it's totally unrestored. They then circle the truck several times rubbing their chin and shaking their head. A few have told me that I'm wrong, it can't be original, no way!
If I were to drive the truck as much as I would really like, it's present condition would not last. And then there is always the risk of an accident (horrors).
Of course, the investment aspect is a big one here also. Chevrolet made more trucks than you could shake a stick at in the sixties, but I'm just guessing there are not more than a handful in this condition left out there. I could be wrong, but I've never seen anything even close, and I've been looking a long time. This equates to return on investment if I should ever decide to sell. More miles = less money, it's that simple.
