I have an '03 ZR2, but not the crew cab. I bought it new in '03 and it has 29,815 miles on it now. The 4.3L V6 is somewhat notorious for head gaskets, but if they don't go by 60-80k, they're probably fine. I just noticed my thermostat housing is leaking, but it's a slow leak and it's an easy cheap fix. It gets shitty gas mileage, I'm not a big fan of the pushbutton 4WD (I liked the manual linkage on the older S-series trucks). My encoder motor (engages and disengages the 4WD) went out, but was fixed under warranty. My TPS was also fixed under warranty. It does have 4wheel disc brakes, a better instrument cluster (MOAR information), and a full size spare when compared against the newer GM light-duty trucks (Canyon/Colorado). The crew cab is basically useless for hauling long stuff though (like motorcycles) - even in my ext cab (longer bed), the tire on my Hurricane was half on the bed and half on the tailgate... but if hauling stuff in the bed isn't an issue for you, then don't worry about it. Overall, the S-series trucks have over 2 decades of development on them, parts are cheap, and they're pretty robust for small trucks... they're just underpowered and suck the dino juice like it's going outta style. I really only do city driving anymore (to and from work) and get 12-13mpg... I got 20mpg on the highway once, but normally if I mix highway it's between 16-18mpg. You should hop on zr2usa.com forum (I used to be active there many many moons ago when it was zr2.com) if you want to peruse the forums over there to see what everyone is bitching about. Just don't mention the Tracker ZR2 model, that's like making fun of someone's buck-toothed mother.
