BMW has been producing cars in the 6 series lineup since 1976. The lineup is comprised of grand tours, which are vehicles designed for long-distance driving. They feature a range of performance attributes compared to other vehicles. During the first generation, the car was only available as a two-door coupe. This first generation was produced from 1976-1989. The second generation wasn’t produced until 2004 - when the 6 series nameplate made a comeback. During this generation, there was a two-door coupe available and a convertible was added. The third generation premiered in 2011 as a coupe, convertible, and four-door coupe (also known as a Gran Coupe). The fourth generation began production in 2017 and has only a fastback body style available. If you have a BMW 6 series, make sure you purchase OEM parts for it. OEM parts are going to fit your car’s make and model perfectly.
