1986 Mercedes-Benz 420 SEL

This long-wheelbase W126 sedan is powered by a 4.2L V8 rated at 201 hp and 228 lb-ft of torque, paired with a four-speed automatic transmission and rear-wheel drive. The SEL designation denotes the extended rear passenger compartment that is a defining feature of this model.

Factory equipment and appointments (typical for a factory-spec 420 SEL)
- Chassis and drivetrain: 4.2L M116 V8 with mechanical/electronic fuel injection, four-speed automatic transmission, rear-wheel drive, ventilated disc brakes at all four corners. Mercedes’ engineered occupant protection—including a rigid passenger cell and front and rear crumple zones—formed the basis of the car’s safety design.
- Exterior: long-wheelbase sedan body with classic W126 styling, full chrome trim and bumpers, rectangular halogen headlamps with integrated fog lamps, alloy wheels, and power-adjustable outside mirrors. A power antenna and cornering lamps were commonly factory-fitted.
- Interior and comfort: full leather seating surfaces with extensive burr walnut wood trim on the dash, center console and door caps. Generous rear legroom and a fold-down rear center armrest (typical of SEL models) enhance passenger comfort. Front seats are power-adjustable with lumbar support; interior appointments include plush carpeting, illuminated vanity mirrors and high-quality switchgear.
- Climate and convenience: automatic climate control for regulated cabin comfort, power windows, central locking, cruise control, and ample storage in the center console and door pockets. A tilt-adjustable steering column and ergonomic instrument cluster were standard equipment.
- Audio and electronics: factory AM/FM stereo with cassette player and an electrically-operated antenna. Instrumentation includes a full set of analog gauges (speedometer, tachometer, fuel and temperature) and a clock; many cars were also equipped with an on-board trip computer as factory equipment or factory option.
- Safety features: three-point seatbelts for all outboard seating positions, headrests, and a focus on passive safety through structure and restraint design. Anti-lock braking (ABS) was available and commonly found on late-production W126 examples.

Condition and mileage
This example shows excellent overall condition and well-preserved factory finishes. It has under 83,000 miles on the odometer, averaging fewer than 3,000 miles per year, reflecting very light use for its age. The mechanicals, interior surfaces, and exterior trim present in a manner consistent with a carefully maintained vintage S-Class.
