What would you guys do??

I'm always looking for mopar parts and/or cars, I actually went to look at a car listed in the local paper (70 Dart) It was a rust bucket but they had another car that caught my attention. (Sorry no pics didnt have camera with me)
It was a 70 Duster Body, typical mopar rust, worst places were left quarter and front floorpans. The front sheet metal had been replaced from another car, but the rest is still wearing its original sassy grass paint. The interior is pretty bare no seats or headliner, has a decent dash, door panels are there but not in great shape. The interior trim..ie kickpanels, sailpanels, a-pillars are still in place and in good shape.
No Eng or Trans, it was an original 6-banger, but someone had been working on this car.. it had the 73-up spool mount v8 k-member in it, and disk brakes, and had an 8 3/4 rear end in it. Also has clutch pedals and a 4 speed hump sitting in the car. All glass and trim is in usable shape also. I think it would be a worthy project, but it does need alot of work and parts. She wants 500 firm for it.

I would like to have it my first instinct was to jump on it, but I still have to finish my charger project, but I hate to pass it up, if nothing else I wanna buy it, stick it behind the garage and maybe save it for my next project, and plus I have a friend that bought a 75 duster for parts, for 40 bucks (no **** forty bucks! He bought it for 1 quarter glass) So I could get some things of it for little or nothing, like seats and stuff.

So what would you do??? Buy it and save it, buy it and part it on eBay or just pass it on and buy 500 worth of goodies for the charger?
