Mazda MX-5 (ND)

MX-5 Miata RF, power retractable fastback, 2017 model year onward The RF swaps cloth for a power-folding hard roof that stows in about 13 seconds at the push of a button, leaving the rear buttresses in place. With the roof open it feels closer to a T-top than a true roadster, but a hard roof stands up better to years of parking outside, and its trunk, at about 4.5 cubic feet, is almost exactly the soft top's size. Expect to pay about $2,700 more than a soft-top Grand Touring and to carry about 100 extra pounds. Choose it if the car lives on the street or you want a snug coupe on cool mornings; choose the soft top if you want the full sky.
