The color is Dark Claret with same color leather interior. It's a respray, unless GM painters suck way more than I'd like to think, but the original color code (1980 code 76). I love the color as it looks different in differing light.
The wheels are older Cragar (Prostar? Streetstar?) With the too-wide tires on back the whole car looks old-school "Hot Wheels/Matchbox car come to life". Maybe not the way I would have done it, but the PO did, and I've really grown to love it.
Plus I love photos of these C3s as they seem to hide all the minor flaws!
