Is this a gold Corvette (as in it's painted a gold color) or is it a Gold Corvette, as in a Bloomington Gold winner Corvette? If the former, look for all the usual used car issues and functioning electrics. If it's the latter, and it's been cared for since it's Bloomington-ization, you probably won't have to look at anything except the price, because a Bloomington Gold standard 'Vette is pretty much a new car.
On a more serious note, many later unrestored 'Vettes tend to be in a parlous state, because a Corvette is still a car to be aspired to, and they've gone through the typical used sports car cycle of slightly less well heeled owners doing less and less maintenance. Check for bad fiberglass repairs (surprisingly, many shops still can't deal with it correctly), and any damage to the chassis. The acutating motors for the headlights and that weird flap over the windshield wipers tend to fail, too. And leather interiors are available, but cost a fortune.
