I purchased my 1996 Blazer 1 and 1/2 years ago with 108,000 on it. It has been very reliable and has had no major problems. If you maintain these vehicles they will run for a long time. Change oil every 3k, tune ups and make sure to grease all ball joints and fittings etc. Flush coolant as well becuase of the known problems with the cooling systems. I love my Blazer and maintain it very well. Vehicle now has 126000 on it and all I have replaced is battery, alternator, thermostat and a rear end seal.
Having a V6 with 4wd. The ability to tow my jetskis very easily. Reliability.
