I bought this car in 2008 because it was decently priced for a 4WD. I live in Montana where it snows half the year and I needed 4WD to be able to get out of my driveway every day to go to school. This was my first car and for about the first year it was good. The only problem I had with it was the alternator, which went bad. Its 4WD is awesome... I could get out of any drifts or ditches I was in. But then problems came at around 120,000 miles. My catalytic converter went out and I had that taken out, and my EGR valve has a build-up of carbon. Every week for the last month and a half I have been having to clean out the EGR valve. My Blazer got about 12 mpg... which is terrible.
I love how the seats in the back fold down, and how much storage space there is in the center console. The seats are broken in so they are very comfortable and the 4WD is very reliable!
I would say that it needs better gas mileage, but it is a 4WD.
