This was my first car when I turned 16, and I loved it.
My dad drove it for seven years before I drove it, and it never left him stranded once. He bought it from a family who had it garage kept with 51,000 miles on it, so maintenance and rust were minimal.
This truck was bone stock, not lifted, not beefed up, and was tougher than 85% of the trucks/SUV out there.
Chevy was not kidding with their advertising, claiming the Blazer was "built like a rock". It drove through 4 blizzards, 2 floods, mud, and in over 100 degree temperatures.
The floods my dad and I drove through had water up to the hood of the truck, and it simply kept going with 4 wheel drive on of course.
It was slow since it had the underpowered 2.8 liter V6, but sure sounded mean as hell driving down the street. It was a challenge to maintain speed, even with your foot to the floor up hills or small grades. However, it didn't have a problem doing 75+ once I installed a better set of Michelin tires though.
The 4 wheel drive system is excellent in these trucks. It was impossible to make it slip, and it would climb/drive through anything you could thing of.
For a 19 year old SUV and my first truck, it looked cool as heck. Midnight Black with a black deer killer bar, fog lights, and a killer black-flame decal in the rear window. Imports feared for their life when they saw this coming down the street.
This truck would refuse to die, and never left me stranded. The parts are extremely cheap for this truck, and can be found anywhere. Not to mention you can fix almost anything yourself on this truck with the simple set of tools, electrical tape, and twist ties.
Interior rattled along with the rear window a little, but that's why I bought a CD player for it.
The mileage was low on this truck, only 135,000 when I sold it, but the wear was above normal due to the thousands of harsh short trips it drove.
You never had to worry about keeping this truck clean, since it had no carpets and a vinyl interior.
Gas mileage was exceptionally good for an SUV; about 24 MPG in the city and 27 MPG on the highway. Sometimes it would be lower or higher, it all depends how you drive.
I still regret selling this truck, and wish I could buy it back to this day. It needed a lot of work, and stupidly I bought a 93 Eagle Talon. The Talon now resides under a cover in my backyard with a blown engine, after I invested close to 3 grand just to fix everything else you could think of.
My suggestion, if you need a great winter beater or off-road warrior, find of these and you will not regret it. If you don't like the 2.8, an engine swap with most Chevy engines out there is very easy. Or you can buy a 88 or newer one with the 4.3 liter engine; just as good.
A good site to check out if you own a Blazer or S10 of any year is www.s-series.org. It is a very helpful site, and is useful for modifying or simply maintaining your truck.
