I built a nice 68 Formula S clone, but now an HO 360 (painted Orange,lol). She's a real smorgasbord of parts,that still proudly wears her slanty heritage, VINs.
If you're going to actually drive your car then you don't want a pristine numbers matching original car. I could never beat the hell out of it and break stuff if the value in the car was its originality.
