Motorsport Monday: 1977 Porsche 935

While most of the headlines of Porsches wins in the 1970s and 1980s focused on the top of the heap prototype victories of the legendary 917 and 956/962s, in the background Porsche ran several very successful production-based racers. I’ve spent several posts showing mid-1970s RSR replicas, all based around the normally aspirated 934 – a racing evolution of the 911. But Porsche went even more extreme in the mid-1970s with the introduction of the 935. Outside of the 917-956 gap and very successful 936 open-cockpit prototype, the car to have in those years if you wanted to win was the 935. Initially developed as effectively a turbocharged 934, the 935 developed a life of its own – stretching the rules to the extreme with some of the most memorable racers like the one race only “Baby” and monstrous winged silhouette “Moby Dick”. There were many 935s made in seemingly endless configurations, but the 935/77s are probably the most remembered. They took a loophole in the rules that failed to specify that on “stock” cars the headlights needed to remain in their original configuration and turned it into an aerodynamic advantage; creating both a design that was more aerodynamic and assisted in cooling and downforce.

Ultimately, the 935s proved nearly unbeatable and many were raced and modified over their life. When the factory moved on to bigger and better projects, privateers such as Joest and Kremer picked up the reigns and ran with the developments. As such, the Kremer K3 and K4 were the highest developed 935s and many racing fans from the 1980s remember the turbocharged monsters spitting flames doing lurid powerslides, their 700-800 horsepower barely tamed by the 956 spec slicks in the rear. While barely recognizable as a stock 911 (the doors are about the only giveaway), the 935 cut its own course through history and is revered by both Porsche and racing fans alike. Today there is a well traveled and rare to see 935 for sale in Germany:

Model history:
Even though Porsche was dominating GT racing in the second half of the 1970s with the 935, the Kremer brothers believed that they could improve the factory built racing cars. Manfred and Erwin Kremer ran a Porsche dealership and in their spare time Erwin successfully raced Porsches prepared by Manfred. From 1977 Manfred stepped up and started to extensively modify the racing cars. In 1978 the Kremer built 935 K2 formed a worthy adversary for the regular 935s, scoring several victories. Another winter of development turned Kremer’s 935 into a world class racing car.

Manfred Kremer’s main focus was on shedding weight. That was one of the main reasons to replace the factory fitted air-to-water intercooler with an air-to-air intercooler. This also eliminated the risk of leaks in the cooling the system. The three litre flat six engine was carried over from the factory built 935s, although in later years a slightly larger 3.2 litre engine was also offered. Depending on the boost level the twin-Turbocharged engine was good for anywhere between 740 bhp and 800 bhp. Power was transferred to the rear wheels through a four speed manual gearbox.

Other improvements included the relocation of the oil cooler and the fuel tank. For ease of maintenance and to enable quick repairs the mounting system of the engine was extensively revised. The shape of the body was also slightly revised adopting the shape of the Porsche Works cars and also the lessons learned in the previous two seasons. Most panels were replaced by high tech composite examples, which alone already sliced 30 kg off the weight. Kremer told legendary journalist Paul Frere that the car incorporated over 100 changes, which made it around 1% more efficient. It does not sound like much, but over a race distance can really make a difference.

Dubbed the Porsche 935 K3, the new racing car was ready in time for the 1979 Zolder round of the German Sportscar Championship. The young and very talented Klaus Ludwig drove the car to a convincing debut victory, beating a colourful field packed with Porsche built 935s. He continued his good form throughout the season, winning a staggering 11 races out of a possible 12. At the Nürburgring he set a lap time of 7.33, which was fast enough to qualify for the last F1 race held on the Nordschleife. Ludwig also headlined the Kremer Le Mans effort and piloted the K3 to its biggest victory together with brothers Don and Bill Whittingdon. It was the first Le Mans win for a real production car based machine, a feat repeated again in 1995 by the McLaren F1.

Porsche completed the last complete 935s in 1979, but continued to supply third parties like Kremer with plenty of parts. The great successes of 1979 sparked much interest and Kremer started to offer complete 935 K3s as well as kits to convert existing 934s and 935s. Manfred Kremer also continued developing the K3 and for 1980 the biggest improvement was a revised body that closely resembled the unique 935/78 ‘Moby Dick’ raced by the Works team in 1978. In the following years Porsche 935 K3s were raced with great success on both sides of the Atlantic. Particularly in the North American IMSA championship the high sprung Kremer Porsches showed their worth by winning many races and the 1980 championship.

Although based on a production road car, the various 935s continued to be competitive even after a new generation of prototype sports racers made their appearance. Kremer anticipated the increased competition by developing the 935 K4. Outwardly similar to the previous cars, it was an altogether different machine. Only the roof and windscreen were carried over from the production car as the unitary steel chassis was replaced by a much lighter and more rigid space frame. The engine was further developed to produce up to 900 bhp. Unfortunately the Kremer brothers had pushed the boundaries a little too far and the K4 suffered often from reliability problems and only managed to win the odd minor race.

Between 1979 and 1981, the 935 K3 scored overall victories at Le Mans, Sebring, Daytona and on the Nürburgring. It must be said that in the late 1970s and early 1980s the interest of manufacturers in sports car racing was at an all time low and the only real competition the K3 faced came from other 935s and the ill-mannered Ferrari 512 BBLM. Nevertheless, the 935 K3 is well placed among the most legendary racing cars and its raw performance is still nothing but awe inspiring.

Specific history of this car:
The car we offer here with chassis number 930 770 0907, was delivered new in 1977 as a single-turbo by the factory to Mr Brambring in Germany. Brambring immediately entered the car in the German DRM championship as well as at prestigious international events, sharing the car with some of the finest German sports car drivers.

In 2002 the active racing career of 0907 finished and the car was sold to a private German collector who had the car on display in his museum until 2013.

Today the car is presented in very original condition, still with its first chassis. The car comes with a correct 935 engine (horizontal fan) and gearbox, now in its latest 935 K3 bodywork. With the car comes a sensational history file which documents the car fro day one! Apart from the Wagenpass and FIA papers there is lots of documentation from the Porsche factory, as well as period correspondence, original racing photos, service records and much more.

This is a great opportunity to purchase a very fine and original factory supplied Porsche 935.

Originally in 935/77 spec, this car outwardly has been updated to the K3 look and some running gear but retains the earlier twin-turbo 3.0 flat six – an interesting choice, since the twin-turbos weren’t as reliable as the single turbos were. The look is incredible; the BBS turbofans are my favorite look on these cars and the color combination is spectacular. The history is equally incredible and features some pretty big names in the list. The price on these car is quite steep to both purchase and run; figure multiple thousands of dollars to run the car a weekend at a minimum, and best guess on the entry price is a million plus. At that price, it will remain a dream car for nearly everyone – but what a car to dream of!


V8 Week Motorsport Monday: Turner BMW/Riley M3 Race Car Pair

I have to admit, I got pretty excited when we first started talking about V8 week. There are so many different cars to choose from; but, it makes “Motorsport Monday” a bit more difficult. “Why”, you say? Well, it turns out that even though most of the marques we feature use V8s in their road cars, not that many of them use them to race with. Finding an Audi DTM V8 Quattro would have been my preferred method of solving this problem, but there just aren’t that many out there for sale. The Mercedes SLS AMG GT3s and Audi R8 GT ALMSs are still a bit too new to come up on the used market, and that really only leaves one option: The BMW M3 V8. Well, at least, that’s what you would think, though the reality is that calling these Turner M3s “M3″ is a bit of a stretch. Tube frame, carbon fiber bodied, M5 powered race cars that look like M3s, sure, but the reality is that these cars share only some dimensions with your road going E9x. Still, since this isn’t “M3″ week, but “V8″ week, I think we’ll allow them – and besides, for the asking price, you get two!

If you’re a fan of Rolex GT or Continental Sports Car racing and a BMW fan, you’ve really enjoyed Turner’s fight against the seemingly overwhelming competition in BMW M3s. I believe I’m correct that these cars have been the most successful M3s over here since the days of the PTG E36 M3s. Tune in to any race they’ve been in and you’re guaranteed to see Auberlen sliding these cars around the way few can, pushing the limits of what he’s been given – and often ending up on the podium. But for Turner the times and rules have changed and they’re moving on, leaving us with not one, but two of their well developed Riley tube frame race cars to purchase. Turner claims 1.6 million invested, and watching the performance over the years, that number is pretty believable. Racing ain’t cheap. But, as we’ve seen in Motorsport Monday features, buying someone else’s old race cars can save you a bundle of money.

That’s not without it’s issues, as again if you’ve been following Turner’s races, you’ve witnessed these cars “trading paint” with some of their competitors, bounce through gravel traps, and fly through the air at inopportune and unexpected times. Despite this, they are simply the best developed “M3″s that you can buy right now. A veritable who’s who of sports car racing has piloted these two cars. They were no expense spared, best parts out there builds. The M5-derived S62 powerplant has proven reliable enough to run in the Daytona Prototype category. Brakes, suspension, wheels, aero, electronics and transmissions are all state of the art. It’s noted that these cars will be eligible for the new rule set with modification, but the future owner would also be able to qualify for other series as well – including BMWCCA racing, NASA, and in the future some vintage race events. Turner has given BMW fans, German car fans in general, and Motorsports fans something special with their run in these cars and watching them has truly been magic.

On a side note, I was also pretty excited as to how many categories these two race cars qualified for – at six individual categories, I may have just set a record. I also have a special connection to Turner; when I was about 14 years old, Will gave me one of my first rides on the track way back when he was an instructor with the BMW club running a then not-very modified E30 M3. It’s really neat to see how far he’s been able to come! Now, grab your 1/2 million dollars and go set some records of your own by owning these great pieces of history!


Ex John Lennon Mercedes 230SL for nearly half a million $

I’ve never been a fan of celebrity cars, with the exception of race cars. You spend gobs of money on them and then park them in a museum or they turn into a Jon Voight’s LeBaron situation.

John Lennon’s 1965 Mercedes 230SL










There seems to always be a John Lennon car for sale somewhere. A few year’s ago his Mercedes 600 Pullman didn’t sell when it reached £190,000 (at the time $273,600) at an auction where it had a £200,000 ($287,600) reserve, tell me if that situation doesn’t sound like some bidding shenanigans. It later appeared for sale with an ask of £320,000.

Now we have an arguably much more mundane Lennon car in this 1965 230SL pagoda that has an ask price of a quite ridiculous $465,000, down from $495,000. The price discrepancy is from varying sites listing the car, the dealership page still has the higher price. The dealer lists the odometer as reading 19,127.

I’m not going to speak about the marketplace for Beatle’s collectibles, but these W113 Benzs continue to rise in value. The Pagodas so called because of their distinctive hardtops are quality cars that garnered a high end clientele when new.

The 230SL was the smallest, in terms of engine options, of the W113 SL. The 2.3 liter inline six puts out 150 horsepower. Ideally you want to find one with the 5 speed manual, but this one was special ordered by John with an automatic.

These are fine cars and in good shape can be seen as investment grade vehicles, particularly the later 280SL. However at this price you could literally corner the market on good driver 230SLs or buy 10 very top tier Pagodas.

Knowing our typical reader on this site, I suspect most of you will turn up your nose at this one, but don’t take it out on the Merc. These were some very quality cars that make for fun drivers. They also aren’t very complicated to work on and are light on a lot of the gadgetry that came in later Benzs. They also are significantly lighter than the R107 SL that replaced them and turned the SL into more of a boulevard cruiser than a twisty road driving car. Just save your money and find a non-celebrity owned one. As with any convertible keep an eye out for water leakage. The Euro models look a lot better with their headlights to me, but eitherway these cars have a great, unmistakably German and Mercedes look.

Prince of Monaco’s 1983 Mercedes 500SEC with 5000 miles

This is what has to be one of the lowest mile, best maintained W126 left in the world.

Perhaps economic hard times are hitting the royalty of the tiny principality, doubtful, but the Prince is selling off a number of cars from his deceased father’s royal collection. The no reserve auction set to take place on July 26 include this beautiful Mercedes 500 SEC.

More and more we see commentary in print and online about the W126 Benzs recognizing them as one of the greatest modern German icons. A recent Jalopnik article had a wonderful line about the W126 that really sums up these cars, “Just stick an old S-class sedan or SEC coupe in a Benz showroom today, and it will look like the proudest car there.” Well said indeed.

The Prince’s 500SEC with AMG accessories doesn’t represent the pinnacle of the W126 in terms of performance or rarity, but the famous ownership and ridiculously low mileage more than make up for that.

This car just looks perfect, the deep dark blue color covers the entire car. The paint has been extended with the standard AMG treatment to cover all the chrome, the grille, the wheels, etc. An AMG steering wheel is inside and an uninstalled set of expensive Recaro buckets is included with the car.

The Prince apparently bought the car new from the Monaco Mercedes dealership and put the limited miles on the car himself.

The sales estimate on the car is listed between $20,000 and $30,000. For the money one can expect a driving experience as if the car was new and certainly, if driven, 100s of thousands of miles of drivability on the reliable V8. The car comes with the original manuals and documentation.

Quite a unique opportunity for this special one owner car.

Be sure to check out the rest of the auction catalog, which includes a nice looking Porsche 928S in German flag colors.

George Foreman’s 2005 BMW 760Li Hits The Market

Boy oh boy, you have to sell a lot of grills to afford a car like this.

The 7 Series cars have never been my bag, too big and too soft for my liking.  But, after driving a ’10 750Li X Drive this week I am starting to appreciate them more.  It may be that I am getting older with my creaking bones appreciating the plush ride the 7 Series provides.  While that may be I am certain I would run into something, or worse yet someone while I fuss with the plethora of gadgets laid out in the most un-ergonomic of ways.

Here we have the biggest of the lot driven by the big man himself for a scant 12k miles.

2005 BMW 760Li:

From the seller -

“Your looking at a vehicle previously owned by the professional boxer George Foreman. This 2005 BMW 760Li is extremely clean inside and out and was rarely driven and always kept in an air conditioned warehouse. On a scale from 1-10 I give this bad boy a 9.8!! Not only does it look great it’s loaded out with Navigation, Rear-Entertainment, Comfort Access, heated & cooled seats, Park distance control, Soft-Close doors, 19 wheels, heated steering wheel and a ton of more upgrades.”

Great looking car, if you are looking for a newer 7 Series but don’t want to fork over $100k for a new one this could be a nice option.  I prefer the 12cyl car to the twin turbo charged 8cyl cars but you really can’t go wrong with either.

The previous ownership does not really do much for the value for this BMW, unless you are a boxing buff.  In which case I have a used ’85 Eldorado that was once owned by Buster Douglas that I can sell you.

With that the $42k buy it now is ambitious, but I have to think a price in the $37k range would be more than fair.  Currently bidding is up to $25.6k with four days left in the auction.
