When we bought ours, it had 52000 miles on it. It was great for a little while, then the transmission went bad (reverse). At 76,000miles, the radiator needed to be backflushed. The front wheel bearings went at 80,000 miles. A rear axle noise started at 81,000. The axle seals were bad when we got it. The rear u-joint was replaced at 60,000. Also had some other minor problems. I would probably never buy another one. I love Chevy, but don't care for the Blazer at all. At least not this one!
The motor is awesome with great pick up. It looks sweet, and the interior controls are convenient.
Transmission, wheel bearings, seals, and many other parts that prematurely wear out!
