I've had my S10 Blazer Sport since 1998. I used to use it as my main vehicle. It was fine and never let me down! The push button 4WD has always worked flawlessly and got me through these rough RI winters! After I got an Accord as my main car, I put a plow on the truck and used it in the winter. It has a lot of power and mobility for perfect plowing. Now after 225,000 miles the engine is still purring perfectly but the body is just rusting out like you wouldn't believe! Although, bondo and new paint did come in handy. I'm thinking of swapping the engine into a newer chassis. The fuel economy is decent and the interior quality is OK, but after all these years, its getting a little ratty.
Push button 4WD. Great power from the V6. Small size for plowing in tight areas, and decent gas mileage.
None really, except the quality of the metals they use on the body and the long term interior quality.
