I have mixed feelings about this vehicle. I bought the truck used in 2000. It has been a fairly reliable vehicle, but it has put us down a few times. Positives: It's fun to drive, has enough room for me, and has good towing power. It's been through off road situations I didn't think it could manage. It has good looks. Major problems: 40,000 or earlier oil lines leak. 70,000 tranny rebuilt-don't buy a new GM tranny, it will only give the same problem, 100,000 Dextron coolant congealed in the radiator and ruined it. At 140,000 the A/C quit and axles or bearings are roaring. Minor issues: Seat levers break, door hinge bushings wear out often (doors sag). In summary, shy away from the Blazer, although I can hardly part with mine.
Great for light off-roading. Perfect size (not too big, not too small).
Design change for tranny, new design for oil lines around filter, change Dextron formula (I think this has already taken place), Better hinge bushings, stronger seat lever posts
