CARS.COM — The third-generation Mazda MX-5 Miata roadster came with a choice of two tops: a manual soft top and a power retractable hardtop, or PRHT. Now, for 2017, joining the fourth-generation manual soft top is what’s called the retractable fastback, or RF. Coincidentally, the fastback aspect is what is not retractable.
Former Executive Editor Joe Wiesenfelder, a Cars.com launch veteran, led the car evaluation effort. He owns a 1984 Mercedes 300D and a 2002 Mazda Miata SE.
