Nice find. Tag rivets look good, 18V interior, black door handles. Same month year and colour as my GTS.
Side windows look a bit bigger than most?

Worth? How good are your body skills? If you need to farm out any work on that then probably worth walking away from and buying one already done. Will end up cheaper.
It would likely sell for $5k or so on eBay with the right description. The individual parts are probably worth more than the car as a whole in reality.
