Roadster

Roadsters were originally two-seater sports cars with no roof, but today the name is given to convertible sports cars. A roadster will generally be a convertible sports car or car with a sporty appearance.

What it means

A roadster is an open-top sports car that is usually small, light and mainly seats two people. Traditionally it has a simple folding soft top or removable hardtop, a compact cabin and little in the way of rear seats or big boot space. The emphasis is on open-air driving and handling rather than practicality, so many classic and modern sports cars are described as roadsters even if the manufacturer also calls them convertibles or spiders.

Why it matters

• Different priorities to normal cars: Roadsters are built for fun and feel, not for carrying families or loads, so comfort, storage and refinement can be secondary to driving enjoyment.
• Extra care for roofs and seals: Like any soft top or convertible, a roadster has roof fabrics, seals and drains that need regular cleaning and proofing if leaks, green algae and wind noise are to be avoided.
• Often enthusiast owned: Many roadsters are cherished toys rather than daily workhorses, so buyers and owners tend to notice paintwork, roof condition and detailing more keenly.
• Body style affects valuation: A tidy roadster with a clean, weatherproof roof and fresh paint generally commands a strong price, while tired roofs, leaks and faded paint can quickly put buyers off.

Where you’ll see it

You will see the term roadster in model names, sales listings and reviews, for example MX-5 roadster, Z4 Roadster or two-seat roadster. Inspectors, detailers and leak specialists may note vehicle type as roadster when talking about roof cleaning, proofing, drainage checks and water ingress, because access and problem areas are often different from those on cabriolets based on saloons or hatchbacks.

Context

Roadster is one of several labels for open sports cars, alongside convertible, cabriolet and spider. In general use, roadster usually implies a two-seat, driver-focused car, where cabriolet often refers to four-seat convertibles based on regular saloons or hatchbacks. Many of the same issues apply across all of them: roof fabric that can go green, seals that can leak, and paintwork that benefits from proper polishing and protection. For specialists, knowing that a car is a roadster helps narrow down typical leak paths, trim wear points and the kind of detailing work likely to be needed on the roof and rear deck area.

Common mistakes

• Assuming roadster is completely different from other convertibles and overlooking that many care and maintenance issues are the same.
• Neglecting regular cleaning and proofing of the roadster roof because the car is only used in summer, allowing dirt and algae to build up between seasons.
• Ignoring damp carpets, misty windows or boot moisture in a roadster, which often indicate early leak issues around roof seals, drains or rear lights.
• Using harsh TFR and stiff brushes on fabric roadster roofs, which can damage fibres, stitching and previous protective treatments.
