Some roadsters became famous, while others quietly disappeared from the automotive spotlight. Their rarity, simple driving experience, and distinctive character can make them especially meaningful to the people who own them. These 19 forgotten roadsters represent the kind of cars that may not attract attention everywhere, but can become nearly impossible for their owners to replace.

Triumph GT6

The Triumph GT6 combined compact British sports-car dimensions with a smooth six-cylinder engine and distinctive fastback styling. Although it was closely related to the Spitfire, the GT6 offered a more powerful and refined driving experience. Its relatively small production numbers and classic proportions have made good examples increasingly interesting to enthusiasts. Owners often appreciate its combination of manageable size, mechanical simplicity, and unmistakable British character.

MGA Twin Cam

The MGA Twin Cam gave the popular MGA roadster a much more serious performance character. Its twin-cam engine provided stronger performance than the standard MGA, while the lightweight chassis retained the model’s traditional roadster feel. Production was limited compared with ordinary MGA versions. Today, surviving examples are particularly interesting to collectors because of their distinctive engine and relatively uncommon status.

MG TF

The MG TF represented the final development of MG’s classic T-Series sports cars. Its body retained the traditional open-top British sports-car appearance while incorporating mechanical improvements over earlier versions. Production numbers were modest, and surviving cars can be difficult to find in original condition. For enthusiasts who enjoy vintage MGs, the TF offers a direct connection to the company’s early roadster tradition.

Jaguar XK120 Roadster

The Jaguar XK120 Roadster combined elegant British styling with impressive performance for its era. Its smooth inline-six engine and long, low body made it one of Jaguar’s most memorable early sports cars. Although the XK120 became an important Jaguar, finding a well-preserved open roadster today is much harder than seeing restored coupes. Its proportions and driving character make it a particularly cherished classic.

Jaguar XK150 Roadster

The Jaguar XK150 Roadster brought a more refined character to Jaguar’s XK sports-car family. It featured a wider body, improved brakes, and a more comfortable interior while retaining the elegant proportions expected from a Jaguar roadster. Production was relatively limited for the open version. Owners often value the XK150 Roadster because it offers classic Jaguar styling without the familiarity of more common collector models.

AC Ace Bristol

The AC Ace Bristol was a lightweight British roadster that combined AC’s elegant chassis and body with a Bristol six-cylinder engine. Its excellent power-to-weight ratio made it a capable sports car long before modern performance technology existed. Only a limited number were produced, and many examples have significant historical value. Its connection to the later Cobra makes the Ace Bristol especially interesting to knowledgeable enthusiasts.

Austin-Healey 100S

The Austin-Healey 100S was developed as a competition-oriented version of the Austin-Healey 100. It featured extensive weight reduction, upgraded mechanical components, and stronger performance than the standard road car. Production was extremely limited, making genuine examples highly desirable today. Owners of surviving 100S models possess one of the rarest versions of the classic Austin-Healey roadster family.

Austin-Healey 100M

The Austin-Healey 100M added performance-focused equipment to the already popular Austin-Healey 100. It included modifications aimed at improving engine performance and handling while retaining the classic roadster layout. Because genuine factory-built examples are uncommon, authenticity is important to collectors. The 100M’s combination of British styling, open-air driving, and sporting upgrades gives owners plenty of reasons to keep one.

Porsche 550 Spyder

The Porsche 550 Spyder became famous through its lightweight construction and competition success. Its tiny body, mid-engine layout, and flat-four engine made it very different from ordinary road cars. Production was extremely limited, and surviving original examples are exceptionally valuable. The 550 Spyder has become one of Porsche’s most recognizable early racing-inspired sports cars and remains a dream machine for many collectors.

BMW 507 Roadster

The BMW 507 Roadster was an elegant two-seat convertible designed for the luxury sports-car market. Its aluminum body, V8 engine, and sophisticated styling gave it a unique position in BMW’s history. Production numbers were very low, and the model was expensive when new. Today, surviving 507s are prized for their beauty, rarity, and importance as one of BMW’s most distinctive classic roadsters.

Mercedes-Benz 190 SL

The Mercedes-Benz 190 SL offered a more accessible alternative to the much more expensive 300 SL. Its elegant body, comfortable interior, and smooth four-cylinder engine made it suitable for relaxed touring. The 190 SL became popular among buyers seeking a stylish European convertible, but surviving examples in excellent original condition are now increasingly valuable. Its restrained design gives it a timeless appearance.

Sunbeam Alpine Series V

The Sunbeam Alpine Series V was one of the later versions of the classic British roadster. Its four-cylinder engine, compact dimensions, and simple convertible layout made it an enjoyable car for everyday sporting drives. Although it never reached the fame of some contemporary British roadsters, the Alpine developed a loyal following. Owners often appreciate its simplicity and the relatively unusual experience of driving one today.

Daimler SP250

The Daimler SP250 was an unusual British roadster with a fiberglass body and a compact V8 engine. Its distinctive styling separated it from more conventional British sports cars of the period. The car’s combination of lightweight construction and V8 power gave it an interesting personality. Production was limited, and surviving examples are uncommon enough that seeing one at a gathering can be a memorable experience.

Alfa Romeo 1900C SS Spider

The Alfa Romeo 1900C SS Spider was an elegant Italian open sports car produced in very limited numbers. Its lightweight construction and coachbuilt bodywork gave it a much more exclusive character than ordinary Alfa Romeo models. Surviving examples are now rare collector cars. Its flowing Italian styling and sporting heritage make it particularly appealing to enthusiasts who prefer uncommon classics over familiar names.

Fiat 1100 TV Trasformabile

The Fiat 1100 TV Trasformabile was a compact Italian roadster based on the versatile Fiat 1100 platform. Its open body and sporty details gave it a character that was very different from larger European sports cars. Production numbers were limited, and surviving examples are uncommon outside specialist collections. Owners often enjoy its small size, distinctive styling, and relatively unusual place in Italian automotive history.

Ermini 1100 Sport

The Ermini 1100 Sport was a lightweight Italian competition-inspired roadster built by Florence-based manufacturer Ermini. It used small-displacement mechanical components but focused heavily on low weight and agile handling. Production was extremely limited, making surviving examples exceptionally uncommon. Its racing connections and handcrafted construction give it a special appeal among collectors interested in obscure Italian sports cars.

OSCA MT4

The OSCA MT4 was a small Italian sports and racing car created by the Maserati brothers after leaving Maserati. It used compact four-cylinder engines and lightweight construction to achieve strong performance for its size. Many were built specifically for competition, making surviving road-going examples particularly interesting. The MT4’s limited production and connection to the Maserati family make it a fascinating forgotten roadster.

Moretti 750 Sport

The Moretti 750 Sport was a small Italian sports car produced by Moretti during the company’s coachbuilding era. Its compact proportions, lightweight construction, and distinctive Italian styling gave it a character all its own. Moretti produced relatively few examples compared with major manufacturers. Today, surviving 750 Sports are rare sights and are especially appealing to collectors who enjoy obscure Italian automotive history.

Abarth 750 Spider

The Abarth 750 Spider combined compact dimensions with the performance-focused engineering associated with Carlo Abarth. Its lightweight body and small-displacement engine made it an entertaining sports car despite its modest size. Limited production and numerous variations have made surviving examples particularly interesting to collectors.
