This 2018 BMW M4 convertible is a Competition Package-equipped example that is finished in Mineral Gray Metallic over Sonoma Beige Merino leather upholstery. Powered by a twin-turbocharged 3.0L inline-six paired with a seven-speed M dual-clutch automatic transmission, the car is equipped with an Active M differential, a folding convertible hardtop, adaptive xenon headlights, 20″ Style 666M alloy wheels, parking sensors, a Head Up display, a Surround-View camera, heated power-adjustable front seats, a heated steering wheel, and iDrive with navigation. Recently acquired by the selling dealer in 2025, this M4 convertible has 51k miles and is offered with a clean California title.
The body is finished in Mineral Gray Metallic (B39) with Shadowline trim, and equipment includes a power-folding convertible hardtop, adaptive xenon headlights, front and rear parking sensors, and quad exhaust outlets. A December 2021 entry on the Carfax report lists “minor damage” with no additional information, and the selling dealer notes a ding in the rear bumper cover and a ding and scratch on the right quarter panel. Close-up photographs of the exterior finish and trim are shown in the gallery below.
The 20″ Style 666M alloy wheels are mounted with Michelin Pilot Sport tires. Braking is handled by blue-finished M-branded calipers over cross-drilled and ventilated discs at each corner, and the car is equipped with M Dynamic Mode as well as an adaptive M suspension.
The cabin features heated power-adjustable front seats upholstered in Sonoma Beige Merino leather. Interior amenities include driver-seat position memory, Comfort Access keyless entry, cruise control, a Surround View camera, a Head Up display, dual-zone automatic climate control, and iDrive with navigation and Apple CarPlay integration.
The heated leather-wrapped M Sport multi-function steering wheel frames a 200-mph speedometer and a tachometer with a variable redline as well as gauges for oil temperature and fuel level. The digital odometer indicates 51k miles.
The twin-turbocharged 3.0L inline-six is mounted behind a carbon-fiber U-brace and was factory rated at 444 horsepower and 406 lb-ft of torque when equipped with the Competition Package.
Power is routed to the rear wheels through a seven-speed M dual-clutch automatic transmission and an Active M differential.
