This 1971 Mercedes-Benz 300SEL 6.3 was acquired by the current owner in 2000 and underwent an engine and transmission rebuild in 2015. In 2018 the bodywork was refinished along with areas of the interior. The car is finished in Dark Red (542) over Palomino leather upholstery and power is provided by a 6.3-liter V8 mated to a four-speed automatic transmission. Equipment includes a self-leveling air suspension, four-wheel disc brakes, 14″ steel wheels, stacked quad headlights, wrap-around bumpers, front bucket seats, air conditioning, and power windows. The odometer now reads approximately 9k miles and true mileage is unknown. This W109 6.3 is now offered on dealer consignment with a car cover, service records, spare fuel injection pump, and a clean California title.
The body is finished in Dark Red (542) and underwent a refinish in 2018. Exterior details include wrap-around bumpers, stacked quad headlights, town and country horns, a Standing Star hood ornament, a power antenna, butterfly-style windshield wipers, a driver’s side mirror, front vent windows, bright trim, and “6.3” decklid badging. The seller notes the left turn signal does not work.
The 14″ steel wheels feature body-color centers and are mounted with Hankook Kinergy ST tires. The car was equipped from the factory with a self-leveling suspension with front and rear air-spring bellows and torsion bar stabilizers. A photo of the car in it's raised and standard height settings are provided in the gallery. Stopping power is provided by power-assisted disc brakes at all four corners. The spare wheel and original jack are no longer with the car.
The front and rear seats were retrimmed in Palomino leather in 2018. Wood trim accents the dashboard and door panels, and additional appointments include driver’s seat-height adjustment, air conditioning, power windows, and a heated rear window. A Pioneer cassette stereo is noted to be inoperable and includes a trunk-mounted Alphasonic amplifier and Pioneer multi-disc CD changer. The right-rear power window, central door locking, and some of the HVAC vent controls do not work along with the air conditioning. The seller notes the dashboard is cracked and wear is visible on the driver heel pad. The front window regulators were replaced in February 2025.
The original black-rim steering wheel frames a 160-mph speedometer, a 6k-rpm tachometer, and a round multi-gauge showing gauges for coolant temperature, oil pressure, and fuel level. Additional features include functional warning lights for the brake, low fuel, alternator, and self-leveling suspension. The five-digit odometer now shows 9k miles and true mileage is unknown.
The 6.3-liter M100 V8 was factory rated at 247 horsepower and 369 lb-ft of torque when new, making it the fastest production sedan of the era and beating big block Corvettes in drag races. The 6.3 powerplant is mated to a four-speed automatic transmission that was rebuilt in 2015. The engine features Bosch D-Jetronic fuel injection, Crane FireBall XR700 electronic ignition, and twin aftermarket resonators in place of the rear factory muffler. The engine was also rebuilt in 2015 along with the transmission. A full service in February 2025 inclluded a compression test, front window regulators replaced, rear brake hoses, fuel hoses at tank, and a new steering knuckle.

@PeoriaBenz Thanks! Corrected that.@mbheritage Roy... don't you mean MB Market? lol. Lovely car! If I were in the market for a 6.3, this would be a great one! GLWTA!Last day for this attractive 300SEL 6.3 auction. I encourage bidders to look at all the images again to fully understand the condition and provenance of the car. The car will be sold as-is with no warranty implied or otherwise. A California buyer will pay all applicable sales tax and license fees unless he/she is a currently licensed automobile dealer in the state. I can house the car at my gallery until the new owner is able to arrange trucking. Payment is to be completed via a bank wire within 3 business days of the auction’s close. Bidders should refresh their browsers regularly during the last minutes of the auction to insure they are seeing the latest bids. It’s generally not wise to try to place bids in the last seconds of the auction. They’re occasionally not processed by MB Market. For those new to the process, be aware that any bid placed in the last 2 minutes of the auction resets the auction clock to 2 minutes. Looking forward to a strong close!$22,000 bid placed by @Simondgb

@handgemacht Thanks for the note. You're hearing the turn signal switch clicking...Welcome to my 1971 300SEL 6.3 auction. As you can see the car presents itself quite nicely although it certainly has a number of the typical 6.3 loose ends, many of which have been noted. Despite having been generally idle for the past few years, It runs and drives surprisingly well with good cold and hot starts and good transmission shift quality. I see negligible suspension bleed while sitting in my facility over the last few weeks. Please have a look all 257 images in the gallery. The repair orders included are definitely worth reading. Image 225 has recent compression readings. The car can be inspected and driven at my facility in Burlingame, CA – 5 minutes south of SFO. Pre-purchase inspections are available locally by appointment. Feel free to contact me directly if you have any questions.$15,000 bid placed by @Tastybenz
What is the loud ticking at idle in the drive video? drive train or valve tickI would encourage a third part inspection! Firstly, due to a costly past purchasing experience, which would have been less so if I were more diligent or if the seller was more transparent. Secondly, the cost of maintenance of the 6.3 and 6.9 is significantly higher than their M117 powered counterparts.$2,500 bid placed by @cory
