Those in the market for car models under the BMW 6-Series should be interested in comparing them with their direct competitors: Mercedes Benz SL, Cadillac XLR, Jaguar XK and Lexus SC430.

Two automobile generations compose the BMW 6-Series. First is the E24 introduced in 1976 as a replacement for the 3.OCS and 3.OCSi also called the E9. The E24, unlike the E9, meets US safety regulations in terms of crash and rollover standards. A 3210 cc engine with 197 PS (145 kW) powers the original E24, which was upgraded to a 3453 cc SOCH, 218 PS (160 kW) in the 1980 model 635CSi for a top speed of 222 km/h (138 mph). The second generation BMW 6-Series featured the E63/E/64 variants. The E63 first came out in 2003 with a 4.4-liter, 325 hp (242 kW) engine. In 2004, the 630i was introduced with an inline six-cylinder engine that is more affordable. This was followed by the introduction of the E64, the first convertible model in the BMW 6-Series.

Base MSRP for New BMW 6 Series: $90,000
