My problem would be finding a reasonably priced vehicle that i liked enough to put one in that is also in my price range. Even when i look at late 60's Rancheros the price is more than i want to spend. Hell, I tried to get excited about Mavericks but even that turned me off, pricewise. Being a lifelong Mopar lover if I have that kind of money to blow on a car it's going to be a B-body.
One of the coolest vehicles in the old shop i worked on was a 56 Ford stepside with a 460 tunnel ram that fit under the hood.
