The Camaro was created by Chevrolet to compete with the Ford Mustang, and was introduced for the 1967 model year. The first generation of Camaro was offered as a rear wheel drive hardtop or convertible. A wide range of engine options were fitted to the orginal Camaro, including inline six and V8 units. The first generation was available with a wide variety of factory and dealer options packages, but the three main offerings were the RS, SS, and Z/28 packages. The RS was an appearance package that featured hidden headlights as well as additional bright trim and 'RS' badging. The SS package was a performance package that was offered with a 350 cu.in. or 396 cu.in. V8 engine, improvements to the suspension and drivetrain, as well as 'SS' badging and side striping. The Z/28 was intially an unadvertised package that offered almost race-ready Camaros with an under-rated 290hp 302 cu.in. V8 engine. In addition to those packages, other notable first generation Camaro variants were the dealer-modified Yenko Camaro, the COPO Camaro, and the 1969 Camaro ZL-1, which was a limited production COPO (Central Office Production Order). Due to the Camaro's popularity, it is commonly turned into a Custom vehicle. Chevrolet built the first generation Camaro until 1969, and replaced it with the Second Generation Camaro.
