Well if you DO buy it, there's a place about 5 minutes from me called
www.thefierofactory.com. It's in north Alabama (Harvest). Nice kid owns the place-he bought it from the old guy who built the business after working there for several years. He's got several acres full of nothing but Fieros, and will ship used parts. Does a lot of the Cadillac 4.5 V8 conversions, but would probably have anything you need to get 'er going. There's also a pretty informative forum on his site.
I like the Fieros as well, especially the GT's..
