2007 Chevy trailblazer

Tons of us have 200k+ on the I6 engine. They will go a looooonnnngggg time if properly maintained. My first one prior to wrecking it had 226k still strong. My current one has 218k, no weakness. I've also seen more than a few at 300-400k. The v8 is a different story, but is somewhat rare thankfully.
