Mazda MX-5 Roadster

The Mazda MX-5 is a featherweight, open-top sports car that turns ordinary roads into a grin-inducing playground thanks to razor-sharp steering and an engaging, tactile gearbox. It won’t swallow the weekly shopping or ski bags, but for anyone after pure driving fun and sun-on-your-face weekends, few cars match its sheer charm and value.
