More than 20 years after its debut, the MX-5 is still very popular. Mazda’s little roadster is equipped with a 2.0L 4-cylinder engine that generates 158 hp (167 with the manual). Each of the three trim levels can be distinguished by their unique style features, as well as their transmissions (one automatic and two manual). The base version comes with a soft-top, though buyers can opt for a hard-top if they prefer.
