Nothing has gone wrong with this car.
I had a 98 ZR2 and liked it enough to buy a 2000. I have never had a problem in the combined year and a half that I owned them. The only somewhat bad comment I have on it is the gas mileage (about 230 miles to the tank). This truck looks really good and handles well on and off road. I love this truck and would definitely recommend buying one.
Just an FYI, I have noticed that this truck has an efficient cruising speed of 55 mph. When I do that highway speed (obviously not on interstates, which I like to avoid) this truck can get 360-400 miles per gallon. When I do Interstates, I go 90 mph, and it can go as low as 190 miles per tank, ugh! I usually get 250 miles per tank in highway traffic.
I've gotten as bad as 16 in town and about 17 hauling 800is lbs of stuff at 70-80 mph, and as good as almost 22 on hwy at about 75-80 avg mph.
