I have an 03 Tahoe Z71 and I love it. By far the best family SUV on the market in my opinion. I had a hard time finding one with less than 200k miles. Found a lot that had over 300k. So there's no doubt they last. There are a few common issues with them but nothing major. Fuel pumps are notorious for failure. I'm going to be replacing mine soon, before we go to WV skiing. It has almost 130k on it now and I don't want to be sitting on the side of the interstate in the middle of the night with a bad fuel pump. I'm planning on replacing it every 125-150k whether its good or bad. My other half is bad to run it with 1/8-1/4 tank of gas in it. I've told her over and over that keeping it above 1/2 will make the pump last longer but she doesn't listen. The other common issue is the cable window regulators are bad to chew up the cable. Other than the leather seats not lasting, that's about it. Can't beat them. Make sure the lift supports on the rear gate are good. She didn't bother to tell me they were getting weak until the gate fell on her head the other day. Found a company in SC on ebay that sold me two strong arm supports for $32 to the door. They were 29.99 each locally.
