Heck, I haven't ever understood why GM/Ford/etc. doesn't re-create their iconic cars but using modern production. They'd sell like hotcakes (the current crop of muscle cars proves that), but they could be much better than the originals for daily driving/sustainability. Give them a limited run number and watch the sales continue to climb.
But I'm dreaming. I openly admit I have a fondness for the past that I tend to project on folks who care nothing for it. Honestly, that's one of the things I love about photography; I get to share that vision (kind of how I see the world) with other folks. They seem to get it, if only one frame at a time.
Trouble is, they wouldn't sell like hotcakes. A handful of people (like you and me) would appreciate them, a smattering would buy them, but not enough to sustain production. But it's a moot point, since they'd never pass the crash tests and safety standards of today.
However, if you wanted to make a one-off, body-on-frame car in the style of the 1930's (my favorite classic era), all you'd need is an F150 chassis with one of those 300 cubic inch inline sixes and a manual transmission. Cut the body panels on a CNC machine and hammer them into shape over a wooden mold. Presto!
