I am looking to buy a used 03 Trailblazer, I would be getting it from a friend, so I'm getting a very good deal, but I'm a little leary because it has pretty high milage. How many miles can I expect to get out of the life of a 03 TB?

Hi sstraate, I would expect the normal life of this vehicle to be about 150k miles. Then you'll start to see parts fail just through normal wear and tear. Hope this helps!
