Now available for auction is this 1971 Mercedes-Benz W109 300SEL 3.5 finished in Tunis Beige Metallic over a dark brown leather interior. Introduced at the Frankfurt Auto Show in 1965, the W108/W109 models filled the role as Mercedes’ flagship S-Class luxury sedans, carrying on from its W111/W112 “Fintail” predecessors. The more luxurious long-wheelbase variant, the W109 offered an air suspension system, premium burl walnut trim, power windows, and an automatic transmission. Carrying the M116 3.5L V8 engine, this 1971 example is said to have spent its entire life in Southern California and has been cared for by three prior owners. Showcasing a freshly reupholstered interior, this 300SEL has undergone a recent full service and is now being offered for auction accompanied by its original owner's manuals.
This 300SEL 3.5 is finished in Tunis Beige Metallic (462) with chrome brightwork throughout the exterior. Some features of the long-wheelbase W109 include vertically stacked Bosch halogen sealed beam headlights, a hood-mounted vent for the cabin filter, and an automatic power antenna. The seller does note some minor clear coat issues on the roof near the driver’s side, and some rust on the lower rear passenger quarter panel. Detailed images are available in the gallery. The factory 14” steel wheels feature color-matched hubcaps and are currently dressed in Cooper Response Touring tires which are said to retain approximately 70% tread.
The interior has been recently reupholstered by GAHH of Hollywood, CA with all new dark brown leather. W109-specific burl wood trim adorns the dashboard, windshield sill, upper door panels, and inner window frames. Standard features of this premium model include power windows, air-conditioning, an analog clock, and a locking glove box. A newer Clarion head unit has been installed and the original Becker radio is said to accompany the sale. The seller confirms all gauges and accessories to be working properly at this time.
The 300SEL is powered by a 3.5L M116 V8 SOHC engine with Bosch D-Jetronic fuel injection, producing an output of up to 190 HP and 240 lb.-ft of torque when new. Power is sent to the rear wheels through a 4-speed automatic transmission. The W109 is renowned for its supple ride, provided by a double-wishbone suspension and air spring system. Four-wheel power-assisted disc brakes were also standard on this model. The seller reports this W109 to be in great running and driving condition with no leaks, cooling issues, or smoke upon startup. The seller does note that the self-leveling air suspension will begin to leak after sitting idle for several days, but will inflate to proper ride height after about 10 minutes of use. Recent maintenance includes an air conditioning service, new fuel lines, new drive belts, and an oil and filter change.
This sale will include the original owner's manuals, radio, spare tire, and a clean title. An exceptional value for a classic Mercedes-Benz, this 300SEL 3.5 represents a bygone era of unprecedented quality and craftsmanship. Do not let this opportunity pass you by.
