Mercedes 300 Adenauer

Otherwise known as the W186, the 300 Adenauer by Mercedes was produced between 1951 and 1957. With comparisons to Maybach, the 300 Adenauer was Mercedes’ most significant and most prestigious vehicle.

Three versions of the 300 series were produced in succession as 300a, 300b, 300c. Equal in features, price, and performance to the rival Rolls-Royce Silver Cloud, the W186 held its own. 

Politicians and business leaders loved the look of 300 Adenauers. To complement the car’s consumer base, glass partition, VHF mobile telephone, and dictation machines were included in various models. 

Konrad Adenauer inspired the name of the 300 vehicles as he employed various versions of the W186 and 189 during his tenure as Chancellor of Germany. Custom features continued with writing desks, sirens, curtains, and even sunroofs. 

The 300 Adenauer was technologically advanced as it shared many design innovations and components similar to the iconic 300 SL with the supreme engine, suspension, and chassis. 

300a Model

Four-door 300’s were introduced at the Frankfurt Motor Show in 1951 and entered series production the same year. 300’s were made available in saloon and cabriolet models with top of the line bodywork. New 3.0-liter overhead cam, aluminum head M186 straight-six was coupled with a 4-speed manual gearbox. 

With a design aimed to give reliable service under prolonged use, the 300 engine had deep water jackets, thermo controlled oil cooling, copper lead bearings, and a hardened crankshaft. Under most conditions, the 300 could sustain cruising rates up to its top speed. 

Solid handling on the 300 was achieved through combining a rigid X-shaped ovoid steel tube frame with four-wheel independent suspension. All around hydraulic drum brakes were present while recirculating ball steering came into play during 1952. 

300b Model

Introduced in March 1954, vacuum-assisted power brakes, and front door vent windows were added. Engine power was increased to 125 PS via different Solex carburetors with an increased compression ratio of 7.5:1.

300c Model 

Making its debut in September 1955, a larger rear window was added to the 300c with optional 3-speed automatic transmission. Convertibles ended up costing almost a third more than standard models. 1956 featured the release of a type 300 limo. 

300d Model

300 Adenauer models were aimed at the American public toward the start. The outstanding quality that the 300 Adenauer presented was matched by a high price tag. High profile customers such as Frank Lloyd Wright sported the vehicle and solidified the car’s selective status. 

Consistent improvements led to 300b, and 300c models not long after the initial 300 models were released. 300d models led to an entirely new body with improved ride and increased rear legroom. While the style of 300 models remained ultimately the same, small details brought the car up to date through the years.

A longer hood on the 300d gave the 300 series a more graceful look and provided ample room for an updated 3-liter six-cylinder engine. Bosch mechanical fuel-injection raised horsepower levels to 180. Power steering being standard led to the 300d being a better overall driving experience.

People have been telling me to go look at Dusty Cars and I'm glad I did. One day, I took the family round and met Doug, the place is great. We saw some really nice vintage cars and even got taken for a drive in one of them.

It's been some time since I've been able to do something for myself and I was looking for something that wasn't going to cost me anything, but still give me a pleasurable outing. Dusty Cars was that one outing. I was able to just look around and take in all the cars around me.

Dear Dusty Cars, Thank you for your hospitality in welcoming us into your dealership. My grandson loved seeing all of your vehicles and committed to star saving his allowance in order to buy one as soon as he turns 21. He's not anywhere near where he needs to be yet, but we'll hold thumbs and keep you in mind for that upcoming visit.

Doug was fantastic to us when we first arrived, but after he had to go and do something urgently, we spoke to another worker there who took great care of us too. Their customer service is good!

Upon meeting John at Dusty Cars, we knew we were in the right place to get our new vintage car. The staff was very professional and friendly, they knew everything about all of the cars and were able to help us get exactly what we needed. Thank you for everything you've done for us. We'll definitely be back again.

I particularly love the details that the owners pay attention to. There are very few things better than sitting in vintage car with the smell of the leather seats, seeing brand new dials on the car. It's great to see how much care is put into restoring these works of art.

I was accessing my father's storage garage after he passed away, which coincidentally, was just across the street from Dusty Cars! I knew there was a car in there and thought it must have been a sign from God to take my car there and sell it to them. It was such a nice experience and I'll go back again.

The dealership is a wonderful place to visit. Love the cars, love the people, love the dog!!! Even though I'm not a collector of any kind, there's something special about coming to see the love they put into their restoration process.

I've always been a lover of classic cars, precisely the 1956 Porsche 356 Coupe, which is considered as the grandfather of Porsche. I was filled with excitement when I saw my dream car listed on eBay by Dusty Cars. I could count almost a 100 stunning pictures of this car on display, with the metal components, the 4-cylinder, air cooled engine and the red leather interior all in good condition. Douglas is indeed a professional; his attention to details is flawless.
