Brother had same car, got it with 40k on it and it literally fell apart. He did have the 3.1L engine and blew 3 head gaskets (2nd time we went with a new head and 3rd time we junked it). Junked it at 160k, all sorts of things kept failing. The best was the passlock key system where you can start the car b/c it doesnt recognize the chip. Dad had a 97 and that fell apart too, aunt had a 98, same deal.
Im not a fan of GM cars, IDK how they build their trucks but somehow they hold up and drive nicer than the fords and dodges. We have an entire fleet of chevy/GMC 3/4 ton vans and trucks at work and no real issues.
