1966 Dodge Dart GT - Trying to Determine How Rare
If you want to keep it, make it like you want.
If you are strickly thinking about $$$$$, I say keep it as it is and sell it. If you decide it will bring more $$$ with new fresh shiney paint, then understand most every tire kicker will say BUTttt what's under the paint. Or say... I see a blem, and you paid how many $$$$$ for such?? or, YOU painted it a color I hate, makes me want to puke.
Or paint it and take it BJ since it is so rare!!!! It will be the first 66 Dart GT they sell??
No, really nice solid fun car IF such rings your chimes. It would mine.
Or just be a progressive, and cut it up for a gen 3 hemi!!
OK, so I am no help.
