Audi launched the TT for the 1999 model year. What better way to get a new sports car on people’s radars than to take it racing? It just so happened that the reformed DTM was going to launch for the 2000 season. While Audi did not officially compete alongside Mercedes-Benz and Opel, their cars were on the grid with Abt Sportsline.

Abt entered four TT-Rs for the 2000 DTM season. The cars are not real TTs as they are silhouette tube-frame racing cars. This car is chassis #001 and is powered by a 450-horsepower V8. It was primarily raced by Laurent Aiello, though the TT-Rs did not have great success in 2000.

This car entered private ownership in 2001 and was restored between 2020 and 2021. It now has an estimate of $435,000-$650,000. More info can be found here.

Mercedes Indianapolis

1923 Mercedes Type 122 Indianapolis Racer

This is a Mercedes open-wheel race car. Not a Mercedes-Benz. Not a Mercedes-AMG. Mercedes. In 1922, Daimler started development of a racing engine for the 2-Litre European Formula, which the Indianapolis 500 was going to adopt for 1923. This meant Mercedes could go racing at the Brickyard.

That 2.0-liter inline-four was supercharged and was rated in period at 150 horsepower, but that is, by Mercedes’ own admission, what it made after a few years of development. On the grid at Indy, the motor put out about 125 horsepower with the supercharger engaged.

Mercedes sent four such cars to Indy for 1923. The competition history for this chassis, number 26913, includes:

  • 1923 Indianapolis 500 – 8th (with Max Sailer, although his nephew Karl Sailer drove relief from lap 73 through 200)

The American Mercedes Company held on to the car after the race, and it later changed hands a few times before finding itself entered in the 1936 Vanderbilt Cup. But it was too outdated and did not compete. In the 1950s it was the property of Henry Austin Clark Jr. In the late ’70s it was in a Japanese collection, from which it was purchased by Bernie Ecclestone in 1995. It moved to its current collection the following year.

The car got a $200,000 engine rebuild in 2011 and now has an estimate of $4,150,000-$5,500,000. It also comes with a spare period body. Click here for more info.

Opel Olympia OL38

Well, the OL38 generation of Opel’s Olympia didn’t really look like this. The Olympia went on sale in 1935, and just two years later it was updated to the OL38, which remained in production until being interrupted by the war in 1940. It resumed production in 1947 and lasted through 1949, when a fresh generation debuted.

The OL38 was offered from the factory as a two- or four-door sedan as well as a two-door cabriolet. This car received, what is claimed to be, one-off roadster coachwork by Glaser. Power is provided by a 1.5-liter inline-four that made around 35 horsepower. It was capable of 70 mph.

This car was purchased out of Ukraine in 2014 and later restored. It now has an estimate of $22,000-$33,000. Click here for more info.

Mercedes “SSK”

1929 Mercedes-Benz 710 SSK Roadster by Sindelfingen

The catalog description for this car… does not seem to tell the whole story. Daimler themselves lists a production of 33 combined units of SSK and SSKL cars. The Mercedes-Benz SS saw a total of 111 units. Mercedes goes on to claim that production numbers for any of the “S” models of 1927 through 1933 are difficult to ascertain as cars were being built and rebuilt, with engines swapped around and chassis being shortened.

So RM is saying (I think?) that this car is one of seven examples of the SS that were modified by Mercedes with a shorter chassis. So, yes, it is a short-wheelbase SS (or SSK). But it’s not an actual SSK. Very few original SSKs remain, and most of the extant examples are just shortened SS cars. The price here reflects that. This car has a lower estimate than the stock SS in the sale, at $1,450,000-$2,200,000. A true SSK could bring 5-10x that value.

The car does have a supercharged 7.1-liter inline-six that was capable of over 200 horsepower with the supercharger engaged. It is said that the car was built in 1929 and first owned by a privateer German racer who took the car to the U.S. in the 1930s. It spent over 50 years in the U.S., being restored around 1983. Around 1994, it was restored again in Germany, with the chassis having been replaced at that time (so there’s part of the value loss). You can read more here and draw your own conclusions.

Iso Grifo A3/L Spider

1964 Iso Grifo A3/L Spider Prototype by Bertone

Offered by RM Sotheby’s | Los Angeles, California | October 2024

The Iso Grifo A3/L was designed by Giotto Bizzarrini for Renzo Rivolta. Styled by Giorgetto Giugiaro at Bertone, the A3/L coupe had an aggressive, muscular stance. They even developed an alloy-bodied race car, the incredibly sleek A3/C. This was the convertible variant of the road car – the lone drop-top prototype.

It says it has a “Corvette engine” – later Grifos got a 5.4-liter Chevrolet 327 V8. So who knows I guess (but it sounds like it’s a 427). Buy it and surprise yourself. This car was initially shown at the 1964 Geneva Motor Show and was later sold to an American. It came into its current collection in 1980 and has been hidden away since.

By 1965 things had soured between Bizzarrini and Rivolta, with the former going on to produce the Bizzarrini A3/C, and Rivolta selling the Iso Grifo GL. This car has an estimate of $700,000-$1,000,000. More info can be found here.

W06 SS by Corsica

The Mercedes-Benz W06 is one of the best things the company ever produced. It started with the Model S, which evolved into the SS, or Super Sport (and later the revered SSK). The SS was offered in three guises between 1928 and 1933: the 27/140/200, the 27/160/200, and the 27/170/225. Between all variants, just 111 were produced.

Those different numbers come from the car’s 7.1-liter inline-six, which was equipped with an engageable Roots supercharger. So that naturally aspirated 140 horsepower jumped to 200 horsepower if you pushed the throttle to the floor. As is typical of late, RM’s catalog is light on details as to which engine this has, but based on the model year, it is probably the 140-200 horsepower variant.

As we’ve discovered with other Benzes of the era, when sold in the U.K., the cars were given slightly different model names. In this case “710 SS” (based on displacement) in lieu of SS 27/140/200. The original body on this car was damaged in an accident, and it was re-bodied by Corsica prior to 1934. In 1979, it set a record as the most valuable car ever sold at auction in $320,000. Now it has an estimate of $3,850,000-$4,950,000. Click here for more info.

1902 Haynes-Apperson

Haynes-Apperson was an important pioneer in the American automotive industry. Elwood Haynes built one of America’s first cars (though he would long claim the first) and partnered with the Apperson brothers of Kokomo, Indiana, to found Indiana’s first car company.

Production started in 1898, and they sold a few hundred examples of their 7/8-horsepower twin in 1901. In 1902, the company expanded the line to two models, both twins: the small eight-horsepower runabout and the 12-horsepower car available as a phaeton or surrey, the latter of which is pictured here.

The car cost $1,800 new, and the two-cylinder engine displaced more than four liters. It carries chassis #74 (though it’s unclear how they were numbering their cars) and is thought to be the oldest operational Haynes-Apperson. A former Harrah collection car, it has run the London-to-Brighton route multiple times. It now has an estimate of $175,000-$200,000. More info can be found here.

Bertone-Bodied FIat-OSCA

The Maserati brothers founded OSCA in 1947 and went on to build sports cars and prototypes. But the secret sauce was their tiny little four-cylinder engine, which Fiat would end up using under license. You could get a Fiat 1500 with an OSCA engine. They built just under 3,100 configured as such.

Most of them wore pretty typical-looking bodies (for the period) from Pininfarina. But because this was Italy in the 1950s, there was always the option of coachbuilding. In this case, Franco Scaglione penned the design, with Bertone carrying out the construction. Only two cars were ever fitted with this body, and this was the only one with an OSCA engine.

The 1.5-liter inline-four was capable of 104 horsepower, and this car is freshly restored. It now has an estimate of $400,000-$500,000. More info can be found here.

Grand Prix racing in the 1930s was a pretty competitive era with various countries flinging their best automakers into the field. France had Delage, Bugatti, and Delahaye all competing at one time or another, and Delahaye’s brightest car of the period was the 135, which it took racing in the form of the 135 S.

Just 20 examples of the 135 S were built, and this is the second-to-last. It was campaigned by Delahaye themselves. It competed at Reims with Alberto Divo behind the wheel and later changed hands that season in the U.K., becoming a vehicle for Prince Bira, who won the 12 Hours of Donington in it. Other entries included:

  • 1939 24 Hours of Le Mans – 8th (with Ian Connell and Rob Walker)
  • 1949 24 Hours of Le Mans – 24th, DNF (with Tony Rolt and Guy Jason-Henry)

That 1949 race ended with the 3.6-liter inline-six failed… as no one had rebuilt it since before the prior Le Mans. The car continued to race into the mid 1950s. In 1970 it was purchased by Rob Walker, who raced it in ’39, and restored. It’s remained with his family since. The car now has an estimate of $1,300,000-$1,950,000. More info can be found here.

Philos Torpedo

1913 Philos A-4-M Torpedo

Offered by Aguttes | Brussels, Belgium | October 2024

Philos was based in Lyon, France, and existed from 1912 through 1923. This early car was restored around 2000 and looks like the type of Edwardian car you would see in a children’s movie that took place prior to WWI. It’s so colorful and covered in brass.

This early two-seat Philos is powered by a 1.1-liter inline-four that was rated at eight (presumably taxable) horsepower. The engine was sourced from Ballot. The survival rate for Philos cars isn’t that high, as this is the second one I can recall coming up for sale in the last decade.

It has an estimate of $16,000-$28,000. More info can be found here.
