Mazda MX-5 (ND)

MX-5 Miata soft top, fourth generation, 2016 model year onward The quickest roof on this list: unlatch one handle, push the cloth top back over your shoulder, and it is down in about three seconds without leaving your seat. That ease is the whole point, because you end up dropping it for a ten-minute errand. Weighing well under 2,500 pounds, it is fun at 35 mph, not only on a mountain road. The trade-offs are real: the trunk holds about 4.6 cubic feet, enough for two soft bags but not a suitcase, and a cloth top is a wear item that fades and can tear with age. It starts at around $32,000 new, including delivery.
