The Mercedes Benz 3.5 300 SELis a much more reliable and less complex car to maintain than the identical appearing 6.3 mechanical injected 300SEL while providing plenty of speed with the electronic Bosch fuel injection on a Mercedes Benz 3.5 V8 engine that was also fitted to the 350SL convertible. This car is very quick and as it has four wheel power disc brakes also stops well. This particular 3.5 engine is in very good condition, tarts quickly and runs smoothly with no smoke. The automatic transmission shifts smoothly. The air suspension and power steering is in good condition. The central door locking system works fine. I purchased this car froman elderly gentleman that owned the first Mercedes Benz dealership in Houston in the 1950's. Over the 15 years I have owned the car it has always been reliable and has never broken down. A lot of expensive renovating and restoring was done such as:

About 10 years ago the car body was disassembled with the light, umpers, hrome and front and rear glass and door panels removed. The seats and carpets were also removed. The car was repainted the original color and reassembled with new front and rear windshield seals, new front windshield glass, ll four rubber door seals and trunk seal replaced and a new original rubber trunk mat was fitted. The cabin pollen filters were replaced. Michelin tires.
The radio is original and not working. These radios can be rebuilt by the original maker. The odometer has never worked since I owned the car and shows around 34K miles. I reckon the car has around 140K miles. The speedometer and all other gauges work fine. The odometer can be rebuilt but I never got around to it. This car is 45 years old and was built to last. The 300SELis a W109 model and were the last to be hand built by German craftsmen in a special factory Mercedes Benz used for their top of the line models such as the 600 Pullman.
This car would be considered good but the many mechanical updates and refreshing adds more to the true value of the car.
