As a kid who grew up in a house with TWO 1:1 '72 Torinos at the same time, including a FB coupe, get the JoHan stock car, not the ex-MPC.
They are out there in the usual sources, and considering modern pricing, not super expensive.
The JoHan body was clearly intended to be a traditional annual kit, with all street trim, bumper/grille, open hood, etc. the best proportion and engraving in the business, even to their last work. It will be another full generation of 3D before anything off a printer bed will match it.
At some point, though, the concept broke down and their '72 became race-only (this narrative also applied to the S&M '71 Barracuda.)
Add in the curbside interior (might be spendy) and bash the rest with the Starsky + Hutch '76. It's been done by a few modelers with some very credible skills and looks fantastic.
