The 1970 Mercedes-Benz 300SEL 6.3 blends luxury and muscle, pairing a Dark Blue finish with its legendary 6.3-liter V8. This sedan represents the W109 series at its peak, combining refined appointments with mechanical strength.
Exterior and Design
The car wears Dark Blue paint with stacked quad headlights and wrap-around bumpers. A Standing Star hood ornament and “6.3” decklid badging emphasize its identity. Town and country horns, butterfly-style wipers, and a power antenna add period detail. The rear window seal was replaced in April 2024.
Suspension and Braking
Factory self-leveling air suspension remains a highlight, with rebuilt valves ensuring proper function. Torsion bar stabilizers support ride balance. Four-wheel disc brakes provide stopping power, while the steering damper, drag link, and tie rods were replaced in 2024. The power steering pump was resealed and fluid flushed in February 2025.
Wheels and Tires
14″ alloy wheels are fitted with Hankook tires installed in 2024. A spare set of factory steel wheels and hubcaps accompanies the car. These updates maintain drivability while preserving originality.
Interior and Appointments
The cabin features black leather upholstery with modified power-adjustable front seats sourced from a later Mercedes-Benz. Driver memory settings are integrated into the center stack. Air conditioning, central locking, and power windows enhance comfort. Wood trim was refinished under prior ownership, and metal heater levers were installed. A Becker Europa radio with Bluetooth connectivity adds modern usability.
Instrumentation and Mileage
A two-spoke steering wheel with chrome horn ring fronts VDO gauges. The cluster includes a 160-mph speedometer, 6k-rpm tachometer, and combination gauge for coolant, fuel, and oil. The odometer shows 27k miles, with ~2k added under current ownership. Total mileage remains unknown.
Power and Performance
The 6.3-liter M100 V8 was rated at 300 horsepower and 435 lb-ft of torque when new. Bosch mechanical fuel injection supports delivery, with a rebuilt pump and braided fuel lines installed earlier. In 2024, the fuel filter, compressor, clutch, left cylinder head gasket, and engine mounts were replaced. A spare right cylinder head gasket is included. In 2025, the air conditioning system was recharged, ignition points replaced, and alternator rebuilt. A stainless-steel exhaust and muffler were also installed, complementing the four-speed automatic transmission and rear-wheel drive layout.
Documentation and Extras
Factory literature, Mercedes-Benz Club of America magazines, and service records accompany the car. Additional spare parts, including a rebuilt W100-specification fuel injection pump, are included with the sale.
Summary
This 1970 Mercedes-Benz 300SEL 6.3 combines classic elegance with enduring performance. Its Dark Blue finish, refined interior, and powerful V8 highlight the model’s dual nature as both luxury sedan and performance machine. With documented service and thoughtful updates, it remains a compelling example of Mercedes-Benz engineering.
