2007 BMW 6 Series 650i

The 6 Series is BMW's grand tourer, a sleek coupe or convertible that prioritizes style and long-distance comfort over pure track work. It's a relaxed cruiser on the highway, with a smooth ride and a cabin that stays quiet at speed. The steering is precise and the chassis feels composed, though it's more about effortless touring than razor-sharp responses. Inside, you get supportive seats and high-quality materials, but rear seats are tight and the trunk is modest for a car this size. A bigger V8 and standard leather upholstery set the 650i apart from the 645i it replaced, giving you more power and a richer interior. The 4.8L I8 makes 360 horsepower and sends it to the rear wheels through a six-speed automatic transmission, so the convertible feels effortless on long highway cruises.
