Redesigned for 2012, the BMW 6 Series comes with either an inline-six or V-8 engine and is offered in coupe and soft-top convertible variants, both of which seat four. New features include adaptive LED headlights, surround-view cameras and a Bang & Olufsen stereo. The Jaguar XK is the 6 Series' most direct competitor, but you might cross-shop the car against a Mercedes E-Class coupe or cabriolet, too.

The 650i, with its twin-turbo V-8 engine, is covered separately in the Cars.com Research section.
