My biggest annoyance is the crappy plastic latch on the sliding rear window, the big plastic thing on the passenger side rear squeaks and rattles, and the door has gotten tweaked a little so the seal isn't quite right. It now makes a slight air noise that bugs me. My uncle mostly fixed the door by grabbing ahold of it and twisting it, so its better than it was.
Other minor BS, the chrome on the grille directly forward of the joint between the hood and fenders is all shot, the armrest on the passenger door randomly pops off. Its been replaced, the original one was broken but the area it hooks into is damaged so it doesn't quite stay properly. The screws have come out of the exterior door handle, but there are holes with plugs you can just pop out to fix this pretty easily.
As far as mechanical stuff, I had a water pump go around 120k, the transmission started to go around 128 and finally gave out totally at 141k, the AC compressor gave around 125k (front seal, and I suspect a clogged orifice tube). I also had the well known 4.3 fuel pressure regulator failure. Otherwise, its been pretty darn reliable. I've had it nearly 5 years, put some 60k hard miles before it started giving me any trouble. I plan to fix this one, and I'd buy another one.
