I purchased my Blazer at about 40000 miles. And what a let down it has been since. I've actually considered seeing if it was a lemon but by the other reviews on here I'm guessing I should have done the research and expected it. Every thing everyone has mentioned having problems with I have do the same and some more. I'm a college student and constantly breaking the bank on repairs for this. I will never buy a Chevy again. I have spent close to $5000 on repair in 3 years of having it. Gas gauge, ball joints, rotors, bearings, rear axle, pittman arm, seat handle, wiring, lights on the dash, heater core. The repairs take all the fun out of this automobile unless you have deep pockets.
