Rigling-Duesenberg

1933 Rigling-Duesenberg Race Car

Offered by RM Sotheby’s | Miami, Florida | March 2024

Herman Rigling and Cotton Henning were chassis builders during the “Junk Formula” years at Indianapolis. And their racing chassis were logged as “Rigling” in the Indianapolis 500 box scores. The junk formula was supposed to ensure stock-ish engines (in some cases, very stock). No superchargers, limited displacement, etc.

That said, you could still build a scratch-built racing engine and meet the criteria. Enter August Duesenberg, who built a beauty that this car first ran with at Indy in 1931. This car’s Indy 500 history includes:

  • 1931 Indianapolis 500 – 35th, DNF (with Babe Stapp)
  • 1932 Indianapolis 500 – DNQ (with L.L. Corum)
  • 1933 Indianapolis 500 – 13th (with Willard Prentiss)
  • 1934 Indianapolis 500 – DNQ (with Harold Shaw)

Let’s keep in mind that this was running at Indy during Duesenberg’s glory years. For 1933 the car used an engine from a Duesenberg Model Y road car. That engine was damaged by a later owner, who tried to adapt it to accept a Model J engine. That project was never completed.

After a late-90s/early-00s restoration, during which the car was fitted with a Duesenberg Model A engine, it relocated to its current collection in 2011. There are not many Duesenberg-powered race cars out there anymore, and even fewer in private hands. This one has an estimate of $500,000-$700,000. More info can be found here.

Gillet Vertigo

2002 Gillet Vertigo Race Car

Offered by Bring a Trailer | October 2023

Gran Turismo fans know exactly what this is. The Vertigo is the product of Gillet Automobiles of Belgium. They’ve been making versions of it since the early 1990s, and some of them look quite different than others, but this is the most famous one.

The race car (there are apparently a few road cars) was aimed at the FIA GT Championship, and it won its class three years in a row in the late 2000s. Power is provided by tuned 3.0-liter Alfa Romeo V6, and the car features a carbon fiber monocoque and bodywork.

This particular car competed in the 2005 FIA GT series, winning its class at Zhuhai in China. It’s said to be one of three such race cars built. It was later restored by Tony Gillet himself and has about a week left to bid on. Click here for more info.

Update: Not sold, high bid of $94,420.

A6CGS Monofaro

1950 Maserati A6GCS 2000 Race Car by Fantuzzi

Offered by RM Sotheby’s | Amelia Island, Florida | March 4, 2023

The A6GCS was among the final models designed by the Ernesto Maserati before the family company was taken over by the Orsi family. The A6 1500 was a road car that went on sale in 1947. Meanwhile, the sporting derivative, the GCS was also launched that year.

The A6 1500 gave way to the A6G 2000 in 1950, which is why this GCS is equipped with a 2.0-liter inline-six. It wears open-wheel coachwork by Fantuzzi and is one of 14 or 15 to have been built.

It was delivered new in Brazil, where it won its class at a race at Interlagos in 1951. It remained in South America until being discovered in the early 1970s as a project and taken to the U.K., where nothing of note happened to it. It would be restored in San Francisco, remaining with its owner there for over 20 years before being purchased by the current owner in 2004.

No estimate is provided, but this is stated to be one of eight surviving examples. Click here for more info.

Update: Sold $1,088,500.

DKW-Vemag GT Malzoni

1965 DKW-Vemag GT Malzoni Race Car

Offered by Bring a Trailer Auctions | January 2023

DKW was a German automobile manufacturer that was part of Auto Union and lives on today as one of the rings in Audi’s logo. In 1956, DKW designs (and the name) were licensed to a Brazilian company called Vemag. A couple of their cars were just re-branded DKWs, and a few models were distinct to South America.

One of them was designed by Rino Malzoni. These GT coupes were initially developed for racing, and this car is one of three fiberglass-bodied cars built for Vemag’s in-house racing team. It’s powered by a 981cc two-stroke inline-three. This car was raced in-period by Emerson Fittipaldi.

The cars were produced for Vemag by a company called the Lumimari Company and branded as DKW-Vemags. Only a handful of road-going versions were made before Lumimari changed their name to Puma and continued on with a very similar design. To be clear, this car is not a Puma. It is the proto-Puma. DKW-Vemag shut down after 1967. Click here for more info.

Antony Bergamot Race Car

1929 Antony Bergamot Race Car

Offered by Aguttes | Neuilly, France | June 20, 2021

Photo – Aguttes

Automobiles Antony was founded by Louis-Auguste Antony and was based in Douai, France, between 1921 and 1932. Antony’s money came from a family cycle-dealing business, and he was an avid racing driver after the turn of the century.

The company’s road cars were not very popular, but they did find some success on the track. This one-off race car features a lowered chassis, front-wheel-only brakes, and a chain-driven rear end. The original engine was changed based on race regulations and rotated between one (or two) Harrisard 350cc two-stroke twins or a 500cc JAP single. It now has a 500cc Triumph twin.

The Bol d’Or is an endurance race that was open to cars in the 1920s, 30s, 40s, and 50s. This car competed there in 1930, 1931, 1932, 1933, 1947, and 1948, usually with Mr. Antony himself (in his 60s by ’48) behind the wheel. It had four class victories among those entries. Antony only built about 60 cars, three of which were pretty competitive race cars that he kept hidden away for long after his death. This one is expected to bring between $42,000-$66,000.

Update: Sold $49,429.

Inter-State Indianapolis Re-Creation

1911 Inter-State Fifty Race Car

Offered by Bonhams | Amelia Island, Florida | May 20, 2021

Thomas F. Hart founded the Inter-State Automobile Company in Muncie, Indiana, in 1908. Production of automobiles began the following year, and an Inter-State was on the grid at the first Indianapolis 500 in 1911. The cars were pretty good, but financial problems led to the company being reorganized in 1914. They shifted to war production during WWI and never resumed making cars. The new owners sold the factory to General Motors after the war, and the Sheridan was later built there.

In 1911, Inter-State offered two models: the popular Forty and the Fifty, which was only available as a seven-passenger touring car. This is what this car started as, but it was later converted to a replica of the 1911 Inter-State Indianapolis race car.

It uses an Inter-State chassis and a Fifty engine – which was a 6.4-liter inline-four rated at 50 horsepower. It’s a pretty monstrous four-cylinder, and I have either seen this car in person or a very similar Inter-State. But the pistons are about the size of your thigh.

The original car must not exist anymore, as this one was used during the centennial celebration of the 500, where it was driven by Buddy Lazier for a lap around the track. It will sell at no reserve. Click here for more info and here for more from this sale.

Update: Sold $184,800.

Edmunds Midget

1975 Edmunds Midget Race Car

Offered by Bring a Trailer Auctions | April 2021

It’s not every day you get the chance to buy a race car directly from the Indianapolis Motor Speedway Museum. This USAC midget was raced Bev Griffis in 1986 to the first female USAC regional victory. Which is pretty awesome. Not sure about the sponsor she had to put up with while doing it though.

The car was built by Don Edumunds of Edmunds Autoresearch, a race car constructor based out of Anaheim, California. He built about 400 of these of various styles between 1963 and 1981. The car spent time in New Zealand back in the ’70s before returning stateside.

Power is from a 2.2-liter Volkswagen flat-four. The car does two things: it goes or it doesn’t. It has direct drive – no shifting here. Just fire it up and give it a push. It’s a compact little historic thing, but it’ll need a little work to get running. Bidding is underway, and the auction ends this weekend. Click here for more info.

Update: Sold $13,500.

Falls-Eight

1920 Falls-Eight Race Car

Offered by Bring a Trailer Auctions | December 2020

Photo – Bring a Trailer Auctions

The Falls Machine Company of Sheboygan Falls, Wisconsin, was founded in 1901. They made milling machines, and in 1908 expanded into single-cylinder agricultural engines. Their engine program spread, and soon they were supplying engines for automobile manufacturers, like Dort and Elgin.

They built three of their own cars in 1921, and in 1923, they introduced an inline-eight engine. They only built eight of those engines, and three of them were destined for Elgin, who ended up going out of business before using them. Falls ended up building a single car using one of their eight-cylinder engines in 1924. It was thought to be a sedan or a touring car.

That car does not exist. But its engine does. In this car. So this car is said to be a 1920, but it is thought that the race car using the Falls engine was built sometime between 1924 and WWII. It sure has a 1920s race car look to it. It is claimed to have attempted to qualify for the 1923 Indy 500, though no record seems to exist.

The interesting part is that this car was gifted to a young Bruce Mohs in 1944. And from here the story is more well known. Mohs was a big personality, so who knows how much of the story that pre-dates his ownership is actually true or just his story. At any rate, this car has been known for quite some time and was even once owned by Phil Hill.

The engine is a 5.0-liter inline-eight. The whole package sure looks to be the real deal, there just isn’t much of anything known about it between 1924-ish and 1944. Oh well, it’s still cool and eligible for many historic events. Click here for more info.

Update: Not sold, high bid of $39,013.

300SL Sportabteilung

1955 Mercedes-Benz 300SL Race Car

Offered by RM Sotheby’s | New York, New York | December 10, 2015

The Mercedes-Benz 300SL “Gullwing” is one of the “must-have” collector cars for serious collectors. And serious collectors need only apply, because in recent years, prices for 300SLs have skyrocketed from around the $500,000 mark to an easy million. Total production of 300SL coupes was about 1,400 examples. Alloy (or aluminium-bodied) cars are highly sought after and very rare. But this is a different animal.

You’re looking at one of only four factory-prepped steel-bodied 300SL Gullwing race cars. Many Gullwings saw competition, usually in the hands of privateer weekend racers, but this is the real deal. Mercedes-Benz sent this car to their sporting department (or “Sportabteilung”) to beef it up to see what the stresses of racing did to their road car.

The engine is a 3.0-liter straight-six making an estimated 240 horsepower – more than a standard road cars. Other upgrades included a lower ride height, competition exhaust, better brakes, and more. Its factory race history is unknown, but it is believed that the car was used as a trainer by Juan Manuel Fangio, Stirling Moss, John Fitch, and others.

Mercedes sold the car to a guy in Paris who entered it in the 1956 Tour de France, in which the car finished second at the hands of Stirling Moss. The father of the current owner acquired the car in 1966. It sat for 40 years and was only recently “refurbished” to road-worthy condition. It has never been fully restored. It is the first of the four Sportabteilung Gullwings and one of only two known to still exist. It will likely become the most expensive 300SL to ever publicly trade hands.

Lightweight Mustang Prototype

2012 Ford Mustang Boss 302R Lightweight

Offered by Mecum | Indianapolis, Indiana | May 12-17, 2015

We love one-offs and prototypes here at ClassicCarWeekly.net. This is a one-off prototype race car built by Ford. But let’s zoom way out. The Mustang Boss 302 was re-introduced for the 2012 model year (and was built through 2013). The 302R was the race car variant that Ford campaigned in Grand Am’s GS class. There was also the hard-core Mustang Boss 302 Laguna Seca Edition road car that fell somewhere in between.

The 302R was a good race car, but it was heavy. So Ford attempted to homologate a lightweight version that would let teams play with weight distribution. But Grand Am nixed the idea because the 302R was competitive as is. So only one lightweight race car was built – this one.

It uses a race variant of the road car 302’s 444 horsepower 5.0-liter V-8 (even though the car started life as an plucked-off-the-line Boss 302, like all 302Rs). This car was never raced. Instead, it was sent to a Ford dealer in Illinois. It appears to have been kept in the family and is now being offered for sale with an estimate between $125,000-$175,000.

Update: Sold $130,000.
