It's a Cutlass. The seller didn't know that, I guess. Probably a simple fix, its a 3.8 with third row wayback seating. http://spacecoast.craigslist.org/cto/5022121333.html I doubt it's the cady (?) converter.
This could be a good buy for someone. Lots of things could keep it from starting. But for that price it's worth the money for parts.
That would be a score. I'm betting the starter solenoid or the ignition electrical switch. I've done a few of those Eighties/early Nineties FWD GM electrical switches, and too many starters to count.
