Very nice, very clean Blazer that runs and drives excellent. All Blazer-class GM SUVs are powered by a 4.3-liter Vortec V6. Although the redline is 5600 rpm, the power peak of 190 horsepower comes at 4400 rpm. And, with a very useful 250 foot-pounds of torque at 2800 rpm, there's limited need to rev the engine to the redline. GM's 4-speed electronic automatic transmission is standard on four-door Blazers.All power equipment is functioning properly. This vehicle has no known defects. We have found no door dings on this vehicle. The engine is mechanically sound and can be driven anywhere with confidence. I would describe the exterior condition as clean. The interior of this automobile is clean. The mileage represented on this vehicle is the actual current mileage. Great, smooth shifting transmission. There are no records of any prior collision damage. These tires have about 3/4 of their life span left.
