The BMW 7 Series is a line of full-size luxury vehicles produced by the German automaker BMW. Introduced in 1977, it is BMW's flagship car and is only available as a sedan or extended-length limousine. The 7 Series traditionally introduces technologies and an exterior design theme before they trickle down to smaller sedans in BMW's lineup.
There have been five generations of the 7 Series:
BMW E23 (1977–1986)
BMW E32 (1987–1994)
BMW E38 (1995–2001)
BMW E65/E66 (2002–2008).
