The final-year W140 S-Class occupies a special place in Mercedes-Benz history, representing the end of an era when the brand’s flagship sedan was engineered with almost excessive attention to refinement, durability, and presence. This 1999 S420 Long Wheelbase captures that appeal well, offering classic W140 proportions, V8 power, and the kind of road presence that still feels substantial today. This example is made more compelling by its desirable equipment, including the rare Parktronic option, xenon headlamps, rear self-leveling suspension, and multi-contour seats. These features help elevate the car beyond a standard S420 and speak to the high-spec, luxury-focused character that made the W140 such a benchmark in period. Showing 114k miles with a clean history, this S420 presents as a usable flagship rather than a museum piece. For buyers who appreciate the traditional Mercedes-Benz formula; long-wheelbase comfort, understated authority, and overbuilt engineering. This late-production W140 offers a compelling mix of specification, presence, and everyday usability.

Pretty car. Silver is timeless. Looks like soft-close isn't working, judging by the trunk lid. You can pull Fuse #9 to reset it. GLWTA
