Novas used to be a dime a dozen but I get excited if I see one these days. My girlfriend says the perfect birthday present for her would be a 73 Duster.
If you can get your hands on one, and the body and chrome is in good shape and it has all the interior knobs, etc. it’d be worth having.
Mechanical parts to fix up that old GM stuff is dirt cheap. It’s the accessory type things, emblems, decals, mirror, trim that they charge an arm and a leg for.
When I redid the dash on my Impala, I took the whole thing out, had it sanded, then primed and repainted it myself. There was a decal on the inside cover of the glovebox that had weight limits, passenger recommendations, etc on it. I covered that puppy VERY CAREFULLY when I repainted, then uncovered it after the reinstall. New paint, original label. Very kool!
