The Porsche Boxster and Cayman are mid-engine two-seater sports cars manufactured and marketed by German automobile manufacturer Porsche across four generations—as a two-door, two-seater roadster (Boxster) and a three-door, two-seater fastback coupé (Cayman).

A roadster is an open two-seat car with emphasis on sporting appearance or character. Initially an American term for a two-seat car with no weather protection, its usage has spread internationally and has evolved to include two-seat convertibles.
