The C215-generation Mercedes-Benz CL-Class was, from its inception, a statement of absolute dominance--a pillarless hardtop coupe that combined the opulent luxury of the S-Class with a silhouette of unmatched grace. As the flagship of the Mercedes-Benz lineup, it revived the grand tradition of the heavy, high-speed German cruiser. But in 2006, the final year of production for this generation, the formula had been perfected. The CL55 AMG represented the ultimate duality: a car capable of crossing continents in hushed comfort, yet possessed of a violence in acceleration that could embarrass contemporary supercars. It remains one of the most beautiful modern designs to leave Stuttgart, famous for the way its windows retract completely to leave an uninterrupted opening from A-pillar to C-pillar. The cocktail only gets more potent when you inspect the engine bay, which houses one of the most revered powerplants in AMG history: the hand-built M113K. This 5.4-liter supercharged V-8 delivers a thunderous 493 horsepower and, more importantly, a tarmac-shredding 516 lb-ft of torque. Unlike the high-revving engines that followed, the "Kompressor" V-8 offers instant, brutal surge at any RPM, mated to the bombproof AMG Speedshift 5-speed automatic transmission. The driving dynamics are managed by the sophisticated Active Body Control (ABC) suspension system, a technological marvel that keeps this heavy coupe perfectly flat through corners, defying physics with hydraulic precision. The example offered here is a collector-grade 2006 model, finished in timeless Silver over a Dark Grey leather interior. It has been under the care of a dedicated car collector since 2007, a provenance that explains its extraordinary state of preservation. With just under 43,000 miles on the odometer, the condition is virtually flawless; the exterior paint is rated at a 9.5 out of 10, while the interior is a staggering 9.9 out of 10, retaining the matte finish on the leather and switchgear that is so often lost on these models. Crucially, this CL55 remains entirely unmodified--an "unmolested" example that presents exactly as the engineers in Affalterbach intended. It sits on its original factory AMG alloy wheels wrapped in high-quality Michelin rubber. Mechanical peace of mind is provided by a service history that includes attention to the complex ABC system approximately five years ago. Offering "no secrets" and no deviations from stock, this is a rare opportunity to acquire a low-mileage, final-year example of the supercharged velvet hammer that defined an era of AMG dominance.
