The 2006 BMW M5 remains one of the most ambitious engineering feats in the history of the sports sedan, famously housing a naturally aspirated V10 inspired by BMW’s contemporary Formula 1 program. This E60-generation example is finished in Silver Gray Metallic and boasts a highly documented life, remaining with its original owner until 2022. With 55k miles on the odometer, it represents a well-preserved window into an era where high-revving atmospheric power was the ultimate benchmark for executive performance. Now offered at no reserve, this California-based M5 combines raw mechanical soul with a suite of luxury amenities that define the peak of the mid-2000s sport sedan market.
Silver Gray Metallic with F1-Inspired Aerodynamics
The exterior character of the 2006 BMW M5 is defined by its purposeful “sleeper” silhouette, enhanced by flared fenders, revised rocker panels, and a decklid spoiler. This example is finished in Silver Gray Metallic, a shade that emphasizes the E60’s flame-surfacing design language while maintaining an understated presence. Functional details include adaptive bi-xenon headlights, Park Distance Control sensors, and the signature quad exhaust outlets that signal the presence of ten cylinders. While some minor blemishes and curb rash on the 19-inch Style 166 wheels are present, the car retains its aggressive factory stance, rolling on Bridgestone Potenza S001 tires that highlight its performance-first intentions.
Silverstone Merino Leather and Alcantara Luxury
Inside the cabin, the M5 offers a high-tech environment trimmed in Silverstone Merino leather, which extends across the door panel inserts and the center console. The multi-function front seats are both heated and ventilated, providing tailored comfort for any driving condition, while the rear occupants also benefit from heated seating. Brushed aluminum trim and an Alcantara headliner add a sophisticated, tactile quality to the interior space. Technology is managed via the iDrive system with navigation, complemented by a Shaker-style six-disc CD changer and satellite radio. Comfort Access and dual-zone automatic climate control ensure that this 500-horsepower machine remains as capable as a daily driver as it is on the open road.
The High-Revving Heart of the S85 V10
The centerpiece of this M5 is the 5.0-liter S85 V10 engine, featuring individual throttle bodies and a semi-dry-sump lubrication system. This high-revving masterpiece was factory rated at 500 hp/507 PS and 383 lb-ft/520 Nm of torque, delivering power through a replacement seven-speed SMG sequential transmission. This specific gearbox was installed by BMW of Santa Maria in 2012, ensuring continued reliability for the sequential shifts. Recent maintenance includes a fuel sending unit replacement in February 2025 and a differential fluid flush, maintaining the integrity of the M Variable differential. The variable redline tachometer serves as a visual reminder of the engine’s 8,250-rpm ceiling.
