Both the Mercedes-Benz CL Class and SL Class models are quite close in size, space, and purpose to the 6-Series models, even though they're significantly more expensive than the BMWs.
While the new Mercedes cars—particularly the new SL, and the high-performance SL63 AMG that competes with the M6—offer more visual flair and drama, the BMW models feel as inspiring, capable, and well-equipped.
Those in search of more of a driver's car—without giving up too many of the creature comforts—should consider the Porsche 911.
However you will end up sacrificing some comfort—as well as some of the 6-Series' advanced tech options.
Otherwise both the Jaguar XK and the Maserati GranTurismo offer comparable performance to the BMW, along with plush interiors and a perhaps slightly more exotic look and feel.
