I own a 2003 Trailblazer LTZ, purchased it in 2004 with 21,000 miles on it, it now has 191,000 and drives like the day I bought it. I never owned a vehicle for more then three years before this I purchased the Trailblazer; driving for 45 years I have owned plenty of vehicles. I've been a member GMTNation a few weeks now busy reading all the posts. I have learned quite a bit and with the wealth of knowledge on these forums (much of which is way over my head) I know I'll learn much more. I have already attempted and completed mechanical work I would have never attempted before reading the forums; my next project will be springs and struts. I'll keep you posted on how this turns out. In the meantime I just want to thank all of you for sharing your experiences and knowledge.
