Though most people will rave about the 2006 BMW M6’s powertrain and hardware, the cabin is equally impressive. Inside, up to four passengers will enjoy leather-clad bucket seats, with those in the rear enjoying their own center console and adjustable headrests. Those up front are treated to significantly-bolstered sport seats with multiple power adjustments, while the driver gets to grip the thickly-padded, multi-function steering wheel with paddle shifters. Clearly marked gauges are ringed in silver, and the instrument panel is adorned with either wood paneling or carbon fiber.
