My 77 was originally silver. The paint was not in good shape however and required a respray. That’s said, silver is one color on 2nd gens I just don’t like. If it didn’t need a repaint I might have left it silver but I opted to go black with the charcoal/red decals that would’ve been on silver. White was a close second to the silver and I almost wish I’d gone that route just cause I think it’s sharp.
In any case, it’s your car. If you really want a different color and aren’t planning on flipping it go for it.
There’s a guy on FB that makes his living flipping these cars. He swears by painting them (nearly) all black and adding t tops saying they pull more money. They probably do. He’s a bit of a jerk about it and admitted he’ll take any publicity he can get over it, good or bad, to make more money. My point is, if that’s what you want, go for what makes you happy. I also converted my car from an automatic to a 4 speed cause it’s what I wanted. I very nearly cut hurst hatches into it too but shy’d away from it…for now.
