Rascal's the MAN!

Thats the truth! Best I usually get thought of is "keeper of the scooby snacks"!
Seriously though, I replaced mine not too long ago and for some reason auto parts stores (autozone, advance, oreillys) all when they first pulled up the belt they thought was the correct one, it was single sided and not the right one, I think it was oreillys that ordered me the correct one by simply adding a "D" to the beginning of the part number, so don't let this scare you away from the car, it's not a big deal.
Now that I have a couple more minutes to type, weather stripping isn't really that big of a deal and probably to be expected to need to be replaced. I guess you ask enough people you get every opinion possible, I respect Tuna's knowledge and opinion but I didn't think putting on all new weather stripping was much trouble at all. The headlight issue he mentions is an under 10$ fix and probably an hour and a half of time, quite simple and there are some very good explanations on the web for how to do it.
Ujoints (six of them) I would kind of expect to have been replaced already but one thing to look into along with if they have record of when the opti and water pump were replaced. Opti's did get built a little more solid in the later C4's, although there are replacements that are better enclosed if you do have to replace it that you might want to consider. If the car runs great, I wouldn't worry about the opti, when I bought my 92 I put about 50k on it and then replaced it along with the water pump because the water pump was just starting to go.
Personally I wouldn't be afraid to by a 92 again based on the year, if it's a solid strong running clean car I think that's a decent price, you might be able to do a little better but you could definitely do worse.
One more added thought, not sure how long or hard you've been looking, or what price range, if I did happen to be looking for myself again I'd consider spending just a little more for an LT4 instead of an LT1, if I did go with an LT1 car I wouldn't be afraid of a 92.
