From what you said about that bugeye, it seems like a good deal. A few things specifically to watch out for:
* Make sure it'll pass inspection - borrow an OBD scanner that can check I/M Readiness, make sure it's good.
* Look around the engine bay for mods. These can be good, can be very bad. The guy's probably taken any he may have had there off anyway, though.
* Make sure the thing drives okay. Drive it hard. If you're getting boost cut CEL's or hesitations or anything, that's a signal of badly reversed mods.
* Do a compression/leakdown test. It takes a few minutes if you have the tools.
One last thing - 100k is getting into the land where you need to think about your timing belt. If it hasn't been done, you will need to do it yourself, as soon as you get the car.
If everything checks out, I think you've found a keeper, at a decent price. Good luck,
