The Marcos GT, the basic shape of which carried over long after the model went out of production in 1990, was first introduced in 1964 in 1800 GT form. By 1967 a smaller displacement 1600 GT version was introduced. Then, two years later, they made the available engine bigger, with the Marcos 2 Litre.

The 3 Litre model debuted in ’68 with a Ford V6. In 1971, Marcos produced 12 examples with a Triumph 2.5-liter inline-six and sold them as the 2.5 Litre. That’s what this is. A rare bird indeed. Output was rated at 150 horsepower. All of these engines were originally intended for the company’s new Mantis model. But they were leftover, thus the shoehorning into the GT.

This example was upgraded under current ownership and has just under 80,000 miles. The pre-sale estimate is $17,750-$20,250. Click here for more info.

SS1 Tourer

Offered by Bonhams | Chichester, U.K. | April 10, 2022

The Swallow Coachbuilding Company started building their own cars in 1932. The first model launched was the SS1. Bonhams quotes a total of 2,503 examples produced through 1936. SS, of course, would become Jaguar after WWII and the resulting new associated connotations with “SS”.

The SS1 was powered by a choice of inline-six engines, with this car being powered by the later, larger 2.6-liter unit. There was an SS2 that featured a four-cylinder powerplant. Output in this car was rated at 68 horsepower.

Five body styles were offered, including the tourer shown here. It remained with a single family for about 50 years, being restored early in their stewardship. Now it has a pre-sale estimate of $78,000-$105,000. Click here for more info.

Update: Sold $73,188.

Adler 2.5-Liter Cabriolet

1938 Adler Type 10 2.5-Litre Cabriolet

Offered by Bonhams | Online | June 2021

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.

Lea-Francis was founded by Richard Lea and Graham Francis in 1895. As did many, the pair began by building bicycles and cars came in 1903. Strangely for a company that began by building bicycles, motorcycle production started after cars did. An independent their entire existence, the company folded in 1960.

The 2½-Litre was introduced in 1949 and was built in very small quantities through 1953. In fact, only 77 were built in total. The engine is a 2.5-liter straight-four rated at 120 horsepower. This is the sportiest car Lea-Francis built after the war.

Kind of resembling a Jaguar XK120, this Westland-bodied Lea-Francis is among the most collectible cars that the company built. Coupling with the decent looks and low production numbers, this example with a six-year-old restoration is expected to bring between $50,000-$60,000.

Update: Sold $47,775.

The Fanciest Pre-Jaguar

1939 SS 100 2.5-Litre Roadster by Van den Plas

We’ve featured another SS 100 before, but that was the larger-engined 3.5-litre model. This car is actually powered by a 2.7-liter straight-six (even though it’s called a “2.5-litre”) making 102 horsepower.

The SS brand, as we all know, became Jaguar after WWII and the Nazi connection those two letters had. This particular car is thought to be the final 2.5-litre SS 100 chassis built in 1939 and it was purchased by Van den Plas, the Belgian coachbuilder. But war broke out and they weren’t able to do anything with it until after things had settled down, so this car with this fantastic, Figoni-esque body debuted in 1948 at the Brussels Motor Show.

Van den Plas began in Belgium in 1870 and a British arm, Vanden Plas, opened in London in 1917. Jaguar had a long associated with that brand through its British Leyland ownership and beyond. You can see the underlying SS 100 under the added swoopy fenders – the grille and hood line is still intact.

This car arrived in the U.S. in the late 1980s or early 1990s and it was then restored. It still wears that restoration that shows well. It is one-of-one and will cost you a pretty penny. Click here for more info and here for the rest of RM’s lineup.

Update: Sold $1,402,500.
