I've owned both the Zr2 and the 4dr model. Should have kept the Zr2 and got rid of the 4dr. We went to Fla. on vacation in 04 and it got pretty good mileage(avg. 18.5 at an avg of 75 mph). I've replaced a tie rod end, an idler arm and service engine light was on (under ext. war.), serp. belt, idler pulley and belt tensioner assembly due to sqeeking. Now service engine light is back on and in cold weather the service 4wd light comes on.
4wd in winter, stereo, storage cap. and its a Chevy
