This long-wheelbase sedan is finished in Pearl Gray Metallic (122) with contrasting lower body cladding separated by chrome trim which continues to the front and rear bumpers. Exterior features include a power tilt/slide sunroof, an automatic antenna, headlamp wipers with heated washers, a heated rear window and a power passenger-side mirror. Surface rust can be seen on the front bumper along with scratches, minor dents and various paint chips which have been documented by the seller.

15” Gullideckel wheels have been fitted with a set of Cooper CSS Grand Touring tires measuring 205/65 with 2017 date codes. Minor surface imperfections are visible on the wheels. A full-size spare can be found mounted below the trunk floor along with the original tool kit and factory jack. Four-wheel anti-lock disc brakes are standard equipment with the ABS system recently receiving service in October 2022. Additional maintenance in April 2022 included new pads and rotors on all four corners as well as a brake fluid flush.

The cabin is trimmed in Blue Leather (262) and features matching blue carpets and floor mats with Zebrano wood trim which lines the center console, dashboard and door panels. The wood trim is in good condition showing no signs of cracking. Both front seats are fully power operated and feature two-position memory for both driver and passenger. Additional interior equipment includes automatic climate control, cruise control, power windows, a 100-watt high-performance audio system and the original Becker Grand Prix radio and cassette player. Both front seats show signs of wear. The seller reports that the AC does not currently work and has not been converted from R12 refridgerant.

The leather-wrapped steering wheel frames analog instrumentation including a 160-mph speedometer, a 7k-rpm tachometer, an analog clock and gauges for fuel level, economy, coolant temperature and oil pressure. A digital outside temperature sensor can be seen mounted centrally along the row of warning lights. The six-digit odometer currently shows 168k miles with 157k miles added by the current owner since 1990.

This W126 is powered by a 4.2-liter V8 engine which is factory rated for 201 horsepower and 228 lb-ft of torque. Power is sent to the rear wheels through a four-speed automatic transmission.

Extensive service records from an independent specialist shop are included with the car. Underbody photos can be viewed in the photo gallery and show minimal surface rust.

This 420SEL was reportedly leased by its first owner before being purchased by the seller’s father-in-law in 1990.
