You need to take a look at the car really well. About two months ago I picked up a '93 J30t with 119k on it for $1500. Things to look for:

does the radio work
does the power attena work
front tension rod bushings(leaking = bad)
dash lights
headlights
sunroof operation
all other general items.

These are just some things known to have problems. Parts are not cheap, but if you can do the labor it should be fine. I have had to get my parts from the dealer.
