Rare GTS wiw ???

The car is dark blue outside and inside. It has its original drivetrain, 383 4 bbl, 4 speed, 8 3/4 rear. It has its original radiator, exhaust manifolds, aircleaner, valve covers, console, inland shifter, wheels and hubcaps. It also comes with nos headlight bezels, nos tail light assemblies, three complete sets of chrome trim, new carpet, headliner, and boxes and boxes of nos parts. It is Galen Govier inspected and verified. The fendertag is there but there is no buildsheet. The car is about 99% complete with no hard to find parts missing. It is a project car that has been in dry storage for almost 15 years. The rear quarters were both replaced, one due to damage and the other due to rust. It does need both outer wheel housings repaired or replaced and if full quarters are available I would replace those as well. Both front floorboards have had small patches and were done correctly. The bottom of one trunk extension should be replaced as well. Other than what I mentioned the rest of the sheetmetal is very nice and has no issues. This is definately as sleeper looking as it gets. I thought a 67 Dart GTS with the original 383 4 barrel, 4 speed combo is as rare as it gets in 67, and maybe all year Darts only to be topped by the later year hemi darts and m code 440 darts. This would be a long term project for me and am wondering if this car is worth the investment once it is finished. I've seen a few of these cars bring nearly 50k when done and done right but of course that was 2-3 years ago. The market has changed and I'm not 100% sure I want to tackle this project. I know for a fact I can finish this car and do it right and probably not spend what it would be worth a a finished car. So what is it worth? I already know its worth only what a person is willing to pay for it, but really, what,s it worth a a nice project car and as a finished car?
