An Anthracite Gray W126 300SEL over Palomino leather with a replacement engine and transmission, offered at no reserve on Bring a Trailer.
The W126 S-Class is among the most durable luxury sedans ever built, and this long-wheelbase 300SEL has been kept running with significant investment. It carries a replacement engine and transmission, a refreshed suspension, a sunroof, Gullideckel wheels, and Palomino leather. Bidding is open with seven days remaining and no bids placed yet.

Market data from Classic.com puts the 300SEL market benchmark at $14,928. Recent sales include a 75,000-mile 1989 300SEL at $15,750, while a 39,000-mile 1990 example brought $33,250 on Bring a Trailer in February 2026.
High mileage and cosmetic wear place this one below the benchmark. The replacement drivetrain and new suspension parts help, but 183,000 miles on the chassis, refinished panels, dings, and scratches mean it competes as a driver rather than a collector car. Fair value lands between $6,000 and $10,000, with $8,000 most likely. No reserve means it sells.

The mechanical work is substantial. The seller states the M103 inline-six and four-speed automatic are replacement units that had 30,000 miles when installed in 2017, and since 2020 the alternator has been rebuilt and the spark plugs, fan clutch, camshaft seals, timing chain, and head gasket replaced. Within the past year, the ball joints, wheel bearings, control arms, tie rods, shocks, struts, pads, and rotors were replaced.

The cabin is well kept. The power front seats and rear bench are trimmed in Palomino leather with matching console, door panels, and carpets, and the car has power windows, cruise control, a Clarion CD stereo, and air conditioning converted to R134a. An overhead Garmin navigation unit with a backup camera has been added.

Cosmetics show their age. The car wears Anthracite Gray with gray lower cladding, a sunroof, and headlight wipers, but the hood and fender tops have been refinished, and dings and scratches appear on the body. Underside photos are in the gallery. The Carfax is clean, and the California title is clean. A pre-purchase inspection should check the underbody and the climate control system.

What makes the W126 300SEL unique
The W126 S-Class set the template for the modern luxury sedan. Introduced in 1979, it combined aerodynamic styling, advanced safety engineering, and exceptional build quality, and the long-wheelbase 300SEL offered extra rear legroom with the smooth M103 inline-six. Many examples have covered hundreds of thousands of miles.

Its reputation has kept it in demand. Clean, low-mileage W126s have grown steadily in value, while higher-mileage cars remain affordable entries into classic Mercedes ownership. Recent mechanical work is what separates a reliable driver from a project.
My take
With no bids yet and seven days to run at no reserve, my call is $8,000, with $10,000 possible if bidders value the replacement drivetrain and fresh suspension. What makes it appealing is the investment, since a recently installed engine and transmission and a full suspension refresh make this a well-sorted W126 driver. What tempers it is the chassis mileage and cosmetics, because 183,000 miles, refinished panels, and body dings keep it in driver territory. Inspect the underbody, then bid.
