This 1999 Mercedes-Benz S600 is finished in Black (040) over Grey (518) leather interior and is reportedly one of as few as 20 and as many as 139 units produced for the 1999 model year. The flagship W140 was purchased new by the husband of the longtime owner in Pittsburgh, PA for approximately $137,400 according to the original window sticker. Now showing 98k miles, this final-year W140 sedan is powered by a 6.0L M120 V12 paired to a five-speed automatic transmission. Features include Adaptive Damping System active suspension, heated front and rear seats, automatic climate control with rear-cabin controls, a Bose sound system with a six-disc CD changer, and xenon headlights. Service within the last two years includes replacement of the spark plugs, rear brake pads and rotors, HVAC blower motor, intake manifold gaskets, valve cover gaskets, coolant reservoir, O2 sensor, a new oil filler cap & seal, and a cleaning of the fuel injection system. This single-family owned long-wheelbase W140 is now offered by the selling dealer with recent service, 10 years of paper service records, the original window sticker, factory literature, one key fob and one valet key, a recent Carfax report, and a clean California title.
The exterior is finished in Black (040) and features color-keyed lower body cladding. Additional exterior features include xenon headlamps, headlight wipers, a sunroof, a power antenna, and power-folding mirrors. The car features a S600 specific grill and V12 badging behind the rear doors on each side. The seller notes there are two very small hairline cracks in the rear window around the third brake light as well as a scratch on the driver door. Detailed photos of the paint and body condition is viewable in the gallery below.
Factory 16″ Ronal alloy six-spoke wheels wear 235/60 series Michelin Premier tires showing 2019 date codes. The wheels appear free of major curb rash or other defects. The car is equipped with Mercedes-Benz’s Adaptive Damping System active suspension and sits level in the photos.
The interior is trimmed in Exclusive Grey (518) two-toned leather seats featuring light grey leather inserts, matching door panels, and carpets. Burled wood veneer accents the dashboard, center console, shift knob, steering wheel, and door panels. The S600 features a double stitched leather dash, door cards, and steering wheel. Additional amenities include front automatic dual-zone climate control, heated front and rear seats, rear climate control, an electric sunroof, a Bose Beta sound system, a six-disc CD changer, a console-mounted cellular phone, and a rear window shade. The seller reports that the V12 badge is missing from the shift knob and the center console cupholder and glove box locking mechanisms are sticky.
The leather and wood-trimmed steering wheel frames an instrument cluster that includes a 160-mph speedometer, a 7k-rpm tachometer, and a digital odometer that shows 98k miles.
The 6.0L V12 was factory quoted to produce 389 horsepower, which is sent to the rear wheels through a five-speed automatic transmission. This example includes approximately 10 years of paper service records documenting prior service on the car and a recent fluid service was completed in April 2021. Service within the last two years includes replacement of the spark plugs, rear brake pads and rotors, HVAC blower motor, intake manifold gaskets, valve cover gaskets, coolant reservoir, O2 sensor, a new oil filler cap & seal, and a cleaning of the fuel injection system.
Factory manuals and the original window sticker are included in the sale, along with one key fob and one valey key. The September 2021 Carfax report shows an accident in March 2000 and displays linear mileage history throughout. The car was first registered in PA but has spent the last 21 years in Southern California through its most recent entry in April 2021.

For many, the W140 S-Class represents the peak of Sacco-era legendary Mercedes design and construction. After over a billion dollars in development, the W140 became perhaps the most sought-after and well-loved Mercedes globally; used by heads of state and diplomatic envoys even today across the world. The W140 was refined from its progeny in 1992 and received updates in its last few years including a 5-speed automatic transmission, improved non-biodegradable wiring harness, and a facelifted fascia along with various interior upgrades including cup holders. These later models are the most desirable of the bunch due to their usability and updated styling. Of these later model examples, the 1999 S600 is the king. With development of the W220 on the horizon to replace the long-heralded W140, most buyers were unlikely to drop $150k+ in 1998 dollars on a flagship V-12 that would be replaced by a newer model within months. Thus, very few of these ultra-flagship MBs were produced in North America for the 1999 model year with numbers quoted between 14-139 units; making this an incredibly rare modern MB. The irony here, of course, being that the 2000 W220 is nowhere near as sought after or collectible as a prior-year W140 and those who opted for the 1999 S600 chose wisely. A buyer of this example would be doing the same as this rare, refined, RWD super-saloon is sure to continue to appreciate and has the service history to inspire confident enjoyment for years to come.
