The files are out there, and anyone with a resin printer can print a smooth body.   

If you have a well set-up FDM printer you can still print a body that will be pretty flat after a couple coats of filler primer and Klear if desired.

Fortunately, vintage examples are still around.  And the Fly, which is pretty if oversized.  The Pink-Car is closer to the Revell/Strombecker bodies.

So plenty of options.
