Got the chance to buy a Gsi rolling shell (minus engine, box and front brakes) in good condition for not a lot of money and I'm trying to decide if I should go for it or not. My plan would be to put a saab turbo lump in it for some 'cheap' fun.

Should I go for it? I have 3/4 other projects too but can't resist the lure of a bargain car lol. Anyone done the conversion on here and got advice?
