This 1985 Mercedes-Benz 300SD was originally ordered for delivery in Ontario Canada and is part of a pair of Petrol Green Metallic Diesel “twins” featured in an article both on this site and in an upcoming issue of Mercedes Enthusiast Magazine.  Finished in Petrol Green Metallic (877) over Grey (278) leather, this sedan is powered by a 3.0-liter turbodiesel inline-five paired with a four-speed automatic transmission.  Showing only two owners over 35 years, this well-documented example is accompanied by a binder with over 100 pages of sleeved service records, handwritten notes and receipts going back many years.  Service in the last 5,000 miles includes a rebuild and reseal of the transmission, new EGR module plug, new glow plugs, new chain tensioner gasket, new thermostat housing gasket, coolant system flush, a new heater core, a new wiper relay, a new heater valve, a new radiator, new tie rod ends (left and right), new front brake pads and rotors, new flex pipe for the exhaust manifold and replacement of the valve cover gasket. This W126 shows just under 557k kilometers (346k miles) and is offered by the seller with factory “high-mileage award” badges, factory literature, service records, handwritten notes, a clean Carfax report, and a clean Delaware title.

The car is finished in in Petrol Green Metallic (877) with color-matching lower body cladding, chrome wheel arches and paintwork that is reported to be original.  Close-up photos of the body, lenses, and trim are provided in the gallery below.  The sunroof assembly and seals were replaced in 2015.

Factory 14″ Bundt wheels wear Winterforce tires sized 195/70.  A matching spare with an older Yokohama tire resides in the trunk.

The cabin is trimmed in Grey leather (278) with color-coordinated trim and black carpeting. Factory features include Zebrano wood trim, a power-operated sunroof, central locking, power seats and windows, and an aftermarket Clarion CD stereo head unit.  An aftermarket Zebrano wood console box is also present in the center console.  Power window switches were replaced in 2017.

A four-spoke steering wheel sits ahead of VDO instrumentation including a tachometer, an analog clock, and a 160-mph speedometer, along with gauges for coolant temperature, fuel level, oil pressure, and instant economy. The six-digit odometer shows approximately 557k kilometers (346k miles).  The seller reports that the fuel level gauge reads inaccurately. 

The 3.0-liter OM617 turbodiesel inline-five was factory-rated at 121 horsepower and 170 lb-ft of torque, which is sent to the rear wheels via a four-speed automatic transmission.  The transmission was rebuilt and resealed less than 3,000 miles ago in 2018 and a new EGR module plug was installed.  In 2014-16 the car received new glow plugs, new chain tensioner gasket, new thermostat housing gasket, coolant system flush, a new heater core, a new wiper relay, a new heater valve, a new radiator, new tie rod ends (left and right), new front brake pads and rotors, new flex pipe for the exhaust manifold and replacement of the valve cover gasket.

Manufacturer’s books & literature, and a binder with over 100 pages of sleeved service records, handwritten notes and receipts going back many years are also included in the sale and viewable in the gallery below.

The September 2021 Carfax report shows linear mileage updates and history in Ontario from 1985 through 2019 with no accidents or damage reported.  A video interview with the longtime owner of the car is viewable below.
