Nothing! That was the best vehicle I ever owned. It's a 97 I bought used in 2000 with ~67k on the odometer. It was parked in 2014 with 200k on the odo(if I remember right), and it never cost me any real money. Biggest repair I ever had was the fuel pump.
To get it really road worthy, I'd guesstimate it would take $3k for a shop to do the work. A good bit less to do it myself. It's too old at this point to fool with though. Fix all the stuff that needs fixing, and you're just about due for a catastrophic failure. Or it could go another 100k+ Hard to say, but there's no point in tempting the fates by getting greedy. AFAIC, it served me well, and owes me nothing. Someone left a note on it last year with an interest in buying it. I made a quick look for the title, didn't find it, and forgot about the whole thing. I really should do something with it. It would make a nice beater offroader for a hobbyist. It's too dented up for a "nice" road vehicle.
