Adler was a pioneering German car manufacturer that sold its first car in 1900. They introduced the revolutionary front-wheel-drive Trumpf in 1932. In 1937, the company introduced the Type 10, which is also known as the 2.5-Litre. This would be Adler’s final real new car, as the company chose not to resume automobile production after WWII.

The 2.5-Liter’s namesake inline-six produced about 57 horsepower when new. The streamlined cabriolet bodies were produced by Karmann and allowed the car to hit 78 mph. The model was offered with two- or four-doors and as a coupe, convertible, or sedan.

In all, just 5,295 Type 10s were built through 1940. Only a handful of two-door cabriolets are known to exist, and this one was restored in the 1970s. The car is accompanied by an Adler motorcycle, bicycle, and typewriter so you can own one of each of the company’s products. The package is expected to fetch $170,000-$190,000.

Offered by Bring a Trailer Auctions | April 2021

The BMW 502 was the V8-powered version of BMW’s six-cylinder 501. The 501 went on sale in 1951 and the 502 in 1954. Confusingly, there was also a “501 V8” model sold, with a detuned version of the 502’s.

The 502 was also better appointed than the 501, which made it expensive. They only sold 190 in the first sales year. The standard body style was a sedan, but Baur-built coupes and cabriolets were also available. This car is one of 57 cabriolet examples.

This one is powered by a 3.2-liter V8 sourced from a later BMW 3200L. The 502 was Germany’s first post-war V8-powered car. With a single carburetor, this engine was rated at 140 horsepower when new. The removed factory 2.6-liter V8 is included with the car.

This car was restored between 2011 and 2013, and it looks pretty fantastic. It’s been at Pebble Beach and is being offered out of a museum. The bidding is already at $125,000 as of this writing, and it is scheduled to end two days from this posting. Click here for more info.

Update: Sold $275,000.

Alvis TC 21 by Graber

1953 Alvis TC 21 Cabriolet by Graber

Offered by Bonhams | London, U.K. | December 16, 2020

Photo – Bonhams

In the line of Alvis cars, the TC 21 slots in between the TA 21 and the TC 108G. The TC 21 was produced between 1953 and 1955. The standard body was a four-door sedan, and the factory did not offer a convertible like they did with the TA and would do so later on with the TD and TE.

Power is from a 3.0-liter inline-six rated at 100 horsepower, and that six could push this car to 90 mph. Only 757 examples of the TC 21 were produced, and just six of those were bodied as cabriolets by Swiss coachbuilder Graber. This particular car was displayed on Graber’s stand at the 1953 Geneva Motor Show.

Sold new in Switzerland, this car has been with its current owner in the U.K. for 35 years. This is not a car that comes up for sale often, as evidenced by the long-term ownership of this one, which should sell for between $160,000-$190,000.

Update: Sold $188,358.

Offered by Bonhams | Knokke-Heist, Belgium | October 11, 2020

In the mid-1950s, BMW had yet to have a real hit. They were still pushing Isettas on the German people, and alongside that, they were offering the ultra-exclusive 507 Roadster. Meanwhile, they were trying their hand at a luxury 2+2 with this, the 503.

Produced between 1956 and 1959, the 503 was powered by a 3.2-liter V8 that made 140 horsepower. The car could be had as a coupe or a convertible, and they all had four seats. This is a Series II example, the type of which was introduced in 1957. It featured a floor shifter for the four-speed manual transmission.

Only 413 examples of the 503 were built, and just 138 of those were drop-tops. This example was restored in 2002 and is certain to be its next owner’s ticket to any major car event worldwide. It is expected to bring between $410,000-$530,000. Click here for more info and here for more from this sale.

It wasn’t that long ago that we featured a Glas 1300 GT – the coupe version of this car, which was built by Hans Glas GmbH in Dingolfing, Germany, between 1964 and 1967, when BMW took over. Over 5,000 coupes were made (including 1700 GT models), and the convertible is much rarer.

Power is from a 1.3-liter inline-four making 74 horsepower. This car has the rare five-speed gearbox, and the body was designed by Frua. Drop-tops were introduced in 1965, and only 242 examples of the 1300 cabriolet were built.

This car has known history back to new, much of it spent in Germany. The coupe we featured sold for less than $18,000 earlier this year. This car carries an estimate of $71,000-$94,000. No roof? More money. Click here for more info and here for more from this sale.

FAM Cabriolet Prototype

1952 FAM Cabriolet Prototype

Offered by Bonhams | Bicester, U.K. | August 16, 2020

Photo – Bonhams

Giuseppe Benelli, he of later motorcycle fame, joined forced with Giuseppe Beretta, he of gun fame, to move into automobile territory to help rebuild their respective companies. Benelli was actually in the firearm business at that point in time, and both men’s companies suffered after WWII.

Benelli designed the chassis, and the two men teamed up with Viscount Guglielmo Castelbarco Albani to form BBC. Benelli’s design featured a 21-horsepower, 750cc V-twin mounted ahead of the front wheels. It was air-cooled and drove the front wheels. The perfect economy car for a struggling post-war Italian economy. It could hit 63 mph, and that car still exists today in the Beretta museum.

Beretta bailed on the project shortly after it was built to return his focus on guns. Benelli soldiered on and built two more cars under the name FAM (Factory Auto Motoveicoli). The prototype, this car, debuted at the 1952 Turin Motor Show. Both cars still exist – sort of. One is a bare chassis with an engine. It’s in pretty sad shape; one of the wheels is plywood.

The other has no engine but has the body, as shown above. Both are offered here together as part of Bonhams Bicester motorcycle sale. The pre-sale estimate is $10,000-$18,000. Click here for more info and here for more from this sale.

Update: Withdrawn.

Facel Vega Facellia Cabriolet

1961 Facel Vega Facellia Cabriolet

Offered by Aguttes | Paris, France | March 15, 2020

Photo – Aguttes

Facel S.A. was a French company that got its start building aircraft components. From there they turned to furniture and then automobile bodies. Finally, in 1954, Facel Vega was founded to build complete automobiles. They were like a small, independent, French version of Alfa Romeo. Their cars were luxurious, expensive, and exclusive.

The Facellia first appeared in 1960. It was like a French alternative to the Mercedes-Benz 190SL. A small, sporty car. A new one would’ve fun about $4,000 in the U.S. at the time. The Facellia was produced from 1960 through 1963.

Coupes and cabriolets were offered, with the convertibles coming first. Power was from a 1.6-liter inline-four good for 115 horsepower, but the engines were built in-house by Facel, instead of earlier cars that used Chrysler V8s. This was the car’s undoing.

Pretty much every car had to have its engine replaced under warranty, which ruined Facel’s reputation and ate most of their cash. By mid-1961, a fix was in place for the F2 series of cars, but the company was gone by 1964. In all, 1,045 examples of the Facellia were produced. This one should bring between $43,000-$54,000.

Talbot-Lago T23

1938 Talbot-Lago T23 Cabriolet

Offered by RM Sotheby’s | Amelia Island, Florida | March 6-7, 2020

When Anthony Lago bought out failing Talbot in 1936, he went about turning the company around. A big part of his plan were models like this, the T23. It was one of the first new models introduced, and it was downmarket from the later, extremely grand, models like the T26 and T150C.

Power is from a 4.0-liter inline-six good for 140 horsepower. Dubbed the “Baby Talbot,” the cars still wore fanciful bodies like this one, which was built by the factory but designed in partnership with Figoni.

It wears an older restoration and has a very nice-looking red and wood interior. The bigger Talbot-Lagos command big money. This Baby should bring between $300,000-$400,000… which is still a decent amount. Click here for more info and here for more from this sale.

Update: Sold $250,000.

The Alfa Romeo 6C 2300 was introduced in 1934 and was updated to “B” specification in 1935. That car remained in production through 1938. Different models were offered from the factory, many of which ended up with coachbuilt bodies. The 2300 B Pescara was sold from 1935 through 1938. Only 120 were produced.

This car was bodied by Worblaufen of Switzerland and was first shown at the 1938 Geneva Motor Show. The car was restored by a previous owner in 1983 and has since held up very well.

Power is from by a 2.3-liter inline-six good for 95 horsepower. This pre-war European beauty is expected to sell for between $725,000-$825,000. Click here for more info and here for more from Artcurial.

Pegaso Z-102 Cabriolet

1952 Pegaso Z-102 Cabriolet

Offered by Bonhams | Paris, France | February 6, 2020

The Pegaso Z-102 is Spain’s most dramatic automobile. Produced between 1951 and 1958, the car sold just 84 copies, many of which ended up with beautiful coachbuilt bodies. We’ve featured three of them to this point, including a convertible.

This drop-top Z-102 looks a little more restrained, and that’s probably because it was bodied by the factory. And that is because this is a factory prototype that was displayed at the 1955 Paris Motor Show. It is powered by the earliest of Z-102 engines: a 2.5-liter V8 that makes 165 horsepower. The 2.8-liter version was more popular, and later cars had a 3.2-liter unit.

This is one of five factory prototypes and the only prototype cabriolet. The current owner purchased the car in 2019 and is the car’s third owner from new. The factory body, while more plain than the Saoutchik cars, is still fantastic. This car should bring between $890,000-$1,300,000. Click here for more info and here for more from this sale.

Update: Sold $782,089.
