Some of history s truly great automobiles have been born from engineers working off the clock building experimental projects far from the prying eyes of company brass and the meddling of the accounting department. Especially within large companies radical ideas will surely be nixed if merely presented on paper. One such engineer was Erich Waxenberger of Mercedes-Benz. In the late 1960s Herr Waxenberger came up with the simple but elegant idea of the ultimate factory super sedan. Starting with a standard W109 sedan a car that left the factory with nothing bigger than a 3-liter inline-six and working on his own time he shoehorned in the mighty 6.3 liter all-alloy M100 V8 into the mid-sized saloon. The M100 was designed specifically for the highly exclusive 600 sedan and limousine but Waxenberger believed that not only could he build a superb sporting saloon using the smaller body he could better utilize the specialized production facility that was building these massive engines. He and his team built a prototype and handed the keys over to Mercedes-Benz factory test driver Rudi Uhlenhaut. The legend is that Uhlenhaut had to stop and open the hood at the first traffic signal to see what on earth Waxenberger had crammed into the 300SEL!Buoyed by the enthusiasm from Uhlenhaut the car saw rapid approval by company bosses especially given that the expensive M100 engine could now be sold in another car. The production version of the 300SEL 6.3 featured sophisticated air suspension a four-speed automatic transmission four wheel disc brakes electric windows sunroof opulent wood trim and leather upholstery. Upon its introduction to the public in 1968 it was declared the fastest four-door car in the world and could easily keep pace with American muscle cars of the era. In fact the 300SEL 6.3 could give a contemporary Porsche 911 a serious run for its money. Road & Track magazine declared it merely the greatest sedan in the world . While less expensive than the 600 the 6.3 was still a costly car when new and just 6500 were built between 1968 and 1972. The 6.3 served its purpose as a regular production outlet for the M100 V8 as well as forming the foundation of a legacy of high-performance luxury sedans that Mercedes-Benz still upholds with the AMG line of super saloons.This 1970 300SEL 6.3 is an attractive and understated example finished in Light Ivory (code 670) over red leather upholstery (code 242). It is a very well-maintained and largely original car accompanied by extensive service records from model specialists. The body is straight and clean with an attractive good quality respray over an excellent body. Gaps are factory precise and all four doors operate with that signature vault-like feel. The original bumpers body moldings grille window surrounds and other brightwork are all straight and in good order benefitting from a recent polish. It rides on a set of beautifully finished factory Bundt alloy wheels that lend a slightly aggressive and purposeful look to the otherwise restrained Paul Bracq-penned styling. This 6.3 is in many ways the ultimate sleeper: Understated with only its discreet badging and a slightly wider stance giving the slightest hint at its massive acceleration and 140mph ability.Stepping into the luxurious cabin you may still be hard pressed to realize this is a serious performance car. The atmosphere is very much about comfortable touring over outright sportiness with high quality and attractive leather trim and wood moldings. The leather is believed to be original and presents in very good condition showing a slight bit of wear on the driver s outer bolster but remaining attractive and supple with an inviting light patina. The rear seat is in similar condition showing little use. Wool carpets are excellent as are the door panels and recently refreshed headlining. Beautifully restored wood trim adorns the dash fascia dash top as well as door and windscreen surrounds. It is also equipped with an original Becker Mexico cassette player and correct ivory steering wheel.Mechanically this car is in very sound order and is essentially turn-key and ready to enjoy. Records show the air suspension was fully rebuilt as was the complex fuel injection pump; rebuilt by respected specialist Jerry Fairchild. The steering box was removed and resealed and many bushings and ancillaries refreshed in the chassis. It works as it should and is a strong performing example a very important factor when considering any 6.3. Included in the sale are original books manuals and tool kit along with the extensive service records and factory service information.The 300 SEL 6.3 is a car that should never have existed in its day yet went on to become a legend the father of a line of performance sedans that continue through today. This is a cherished example that has had thousands spent to ensure it continues to thrill drivers for years to come.
This is probably one of the best examples of a 300sel 6.3 currently on the market. It is a 1970 US model that looks very striking in the classic Mercedes Silver/Red combination. I wanted a 6.3 since I was a kid and finally bought this car last summer. You are probably already somewhat familiar with 6.3s but if not, do a quick web search and you’ll find that this was one of the greatest performance cars of its era and beyond. It is the pre-cursor to the current day AMGs and is still a very quick car by modern standards. I’ve put about 10,000 miles on it in the past year. It has been very, very reliable and has never missed a beat on the many road trips I’ve take it on. It is very fun to drive and has a presence that few other cars have. It almost always gets front row parking wherever I take it, even in the midst of Ferraris, modern day Rolls Royce’s, S Class Benz’s etc. A little history on the car. From what I gathered, it had 2 owners prior to my acquiring it. The person I bought it from was the CEO of a biotech company who had it since about 1993 and prior to that it was owned by a wealthy family in the Denver area. I’m happy to give you a little run down on myself also if we talk over the phone. For cars like these, the owner’s background, interests, and financial means are part of the story and will tell you something what you are getting. The reason I bought this car in particular is because it appeared to have never fallen into disrepair or had maintenance neglected. If you are familiar with 6.3s you’ll know that bringing a car out of disrepair or neglect is almost impossible unless you have a lot of money and time to dedicate to the project. By a lot of money, I mean >$100K. There were a lot of cars I saw in the $30K range that superficially looked ok, but had minimal service history, hidden areas of rust and various mechanical and cosmetic items that were in need to repair. Things like the air suspension valves and mechanical fuel injection pumps can only re-built at a handful of places. These, along with a variety of other mechanical parts will eventually need to be sorted out if the car has not been regularly driven. The 10,000 miles I’ve driven in the past year has given me great confidence that all the major kinks have been worked out in this car. My 6.3 has been maintained and serviced at one of the top 6.3 shops in the country, maybe the world. From receipts as well as evidence of previous work done, I would estimate that the car has had something like $100-150K spent on it over its lifetime on general maintenance and repair. Not bad, when considering it is 46 years old. Some of the notable items that I’ve done are: new air suspension, new mechanical injection pump, new starter with points, new window actuators, modern stereo system (reversible), partial repaint (very high quality, car cosmetically looks perfect). I am going to leave my phone number off the main listing because the last time I sold a car, I got more solicitations for other services than parties interested in purchasing the car itself. If you are seriously interested, send a message via the AutoTrader system and let's discuss over the phone. The car is in incredible shape but it is 46 years old and not perfect. I will be happy to go over what I consider the relatively minor imperfections when we speak. That said everything from the clock to the power antenna, lights, sunroof, air suspension, air conditioning etc. work as they should. Even little things like the trunk lock are working and correct. T his is not the typical 6.3 that you find on the market. Most of the cars I saw looked at before purchasing this one looked ok on the first glance but had significant problems with mechanicals or rust when I explored further. These were all cars in the $30 to $50K range. I doubt I could have taken any of them on a trouble-free 500-mile road trip. I'll apologize in advance, but please do not contact me with offers significantly lower than my asking price. I know these cars very well and very few 6.3s of this caliber every come up for sale. This is much closer to the >$200K 6.3 that was recently for sale at the MB Classic Center than it is one of the random cars that pop up for sale now and then with questionable mechanicals and maintenance history. I enjoy driving the car and have no real need to sell it. If you have a classic Benz or an older air-coooled 911, I might be interested in a trade. I have attached a nice set of photos showing the car on various road trips as well as in my neighborhood in New York City and Florida. The car is currently in Florida. I don't mind selling the car internationally provided the buyer takes care of all the logistics. As mentioned before, if interested please send a message via the Autotrader system and let's coordinate a time to discuss over the phone. **Ps. I am in the process of uploading more photos. Most need to be resized as they are higher resolution than the upload file size limit will allow. I hope to have this done within the next week.
