The Chevrolet Blazer (4WD model T-10) and the similar GMC S-15 Jimmy (4WD model T-15) are mid-size SUVs from Chevrolet and GMC respectively. Production began alongside the larger K5 Blazer and Jimmy in 1982 and lasted through 2005. In the United States retail sales of two-door Blazer models ceased in 2004; all other models were sold until April 20, 2005. In the Canadian market, four-door models of the Blazer and Jimmy were sold until the 2004 model year and until the 2005 model year for the two-door models of both. However, the Blazer continues to be produced.
