I've owned my Blazer for 10 years now, original owner. The vehicle has proven to be very reliable, good off road, great towing, and nice on the highways. If I had to do it again, I would still buy this car. The car does have it's design problems: (1) every 40k I've had to pay $350 to get an emmissions valve replaced -- frustrating, (2) even though I have a heavy duty alternator package I've had to replace the battery 3 times -- again frustrating.
Folding back seat -- lays down completely flat. Acceleration -- plenty of torque to beat most all cars off a stop-light.
Emissions control valve -- annoyed that it has to be replaced every 40k miles, otherwise the engine idles terribly.
