The Chevrolet Blazer was one of the first SUVs. Introduced in 1983, it was based on Chevrolet's S-10 pickup truck. Identical to the GMC Jimmy in all respects except some cosmetic details on the grille and rear, the Chevy Blazer was smaller than some of the behomoths 4WDs of the day, such as the Suburban. In 1988, Chevrolet finally upgraded the weak Blazer engine with a 6-cylinder standard motor. Even better was the optional 4.3-liter (also 6-cylinder) engine that boosted horsepower to 150 (later that model year: 160). A 6.2-liter, V8 engine was another option. Air conditioning, cruise control, power locks and windows, and a limited slip differential were options for the '88 Chevrolet Blazer. Interestingly, as many '88 Chevy Blazer owners called the truck powerful as accused it of sluggishness. The truck's fans were often devoted and would praise it to the skies, calling it dependable and buying one after the other. Many owners complained of bad rusting around wheel wells and rocker panels, however; other negative comments include the bouncy ride, poor gas mileage, and mechanical problems such as loose steering and malfunctioning heater core.
