You can always add on stupid stuff if you want, but using modern technology (audio, f'rinstance) carbon fiber (maybe) and exact duplicate molds ... I believe a '57 Chevy Belaire would sell big.
Just a car with a simple AM/FM radio and etcetera for about 20K?
Who wouldn't want one ?
That’d go over like a fart in church with owners of real ‘57s and purists.
