92' S-10 Blazer, to buy or not to buy?

I recently purchased a 1992 Chevrolet S-10 Blazer Tahoe Limited. Since I live in the Northeast I wanted a 4 wheel drive vehicle to get me through the winters. In my search I found this SUV. It is black with the factory fading gray striped graphics which look very sporty and go well with the black body color. There are many available options such as pwr wndws, pwr lcks, snrf, Electronic push button 4 wheel drive (which is worthless), lthr interior, lighted vanity mirrors, over size off road tires and many others. My Blazer also came with the 4.3L Vortec engine which produces 210 horsepower - great for fun driving and towing =) but bad on gas =( Back to the 4 wheel drive problem. As a little reaearch will show, this year model in particular had a problem with the electronic shift transfer case for which a recall was ordered. Mine has had the recall work and still is no help on snow or in wintry conditions. All wheels do engage when 4 wheel drive (4 Hi / 4 Lo) is activated but there is no grip from the vehicle. There was then a new set of BFgoodrich Radial T/A tires placed on with the same result - no go in snow. Other then being a sled in the snow this is a great vehicle, fun to drive and very powerful. A good buy if you come across one for a decent price, Just don't plan to use it for a primary wonter vehicle.
