Gray and red pin striping traces the lines of the car and the bright work shows in good condition. Original Sekurit/Sigla glass is seen throughout the greenhouse of this W126. A small spot of rust is present on the front passenger and driver quarter panel below the corner marker and rock chips are visible on the front of the car. The car has been professionally paint corrected and ceramic coated in preparation for the sale. The antenna motor and mast have been recently rebuilt. 

Fitted are 15” Gullideckel wheels which come wrapped in a set of Michelin Defender T+H all-season tires measuring 205/65 on all four corners with 2018 date codes on three wheels and a 2019 on one wheel. The wheels present in excellent condition since the current owner powder coated them and new lug bolts and fresh center caps are noted on each wheel. All new brake calipers, hoses, fluids, pads, and rotors have been done under the current owner. New wheel bearings were done alongside four new Bilstein shocks/struts and lower control arm ball joints. 

The cabin comes upholstered in Gray Leather (278) and features Zebrano wood trim in good condition lining the center console, dashboard and door panels. Interior features include power adjustable front seats with memory, a power adjustable steering column, automatic climate control, cruise control and an aftermarket VDO Continental with the original Becker included in the sale. All windows have been greased and serviced. The seats show in very good condition with light wear noted on the driver left side bolster. Coco Mats are seen for the front driver and passenger floorboard with berbere carpeting for the rear. Rear reading lights in the C-pillars are shown to operate as intended. The driver black plastic kick panel is not installed but comes with the car. The cruise control amplifier was rebuilt under the current ownership, but will occasionally reset during use. The climate control system comes with a new compressor, R134a conversion, o-rings, dryer, expansion valve, low pressure switch, blower motor, auxiliary fan switch, new refrigerant, and a new heater monovalve. 

The four-spoke steering wheel fronts a 140-mph speedometer along with a 6k-rpm tachometer, an analog clock and gauges for fuel level, coolant temperature and oil pressure. A row of warning lights is placed below with a digital outside temperature sensor mounted in the middle. The six-digit odometer reads just under 153k miles. The steering wheel is power assisted and telescopes only. 

This W126 is powered by a turbocharged OM603 3.0-liter inline-six diesel engine which is factory rated at 148 horsepower and 201 lb-ft of torque.

Underside photos are provided in the gallery showing no rust. The seller states this car was not used during winter and lived indoors its whole life. Preventative clear undercoating was done by the current seller in preparation for the sale. There is a small transmission flare between second and third, but the current seller had an experienced technician inspect the issue and found nothing wrong. 

The Carfax report shows a moderate accident in 1987 and this W126 is registration only as Maine does not issue titles for cars this old. This 300SDL shows just under 153k miles and is now being offered by the current owner out of Kennebunk, Maine with records going back to 2005, the original tool kit, a spare tire, spare parts, Mercedes-Benz specific tools, Tempomat hang tag, stamped service booklet, manufacturer's literature, original radio, a Carfax report and a clean Maine registration.
