Used 2016 BMW M6 for Sale

The M6 Gran Coupe gets a twin-turbo V-8 engine, a 4.4-liter unit that pumps out up to 600 horsepower before topping out as high as 186 mph with the extra-cost Competition Package. A 7-speed dual-clutch transmission is standard, but an honest-to-goodness, old-fashioned 6-speed manual is a no-cost option.
