#MazdaMx-5Rf

In an introductory post last week, I detailed a couple of cars I was considering as a replacement to my decade-old Infiniti M. The comments (some filled with unusual anger) prodded me to add another car to the list.

A week later, I can tell you that two of those former options are absolutely out of the question.

Got $2,755?

That’s how much extra coin Mazda wants in order to swap out the 2017 MX-5 Miata’s soft top, install a pair of buttresses, and replace the soft top with a foldable, targa-style hard top.

You’re not just paying $2,755 extra for the seasonal benefits of a hard top. At least half of those two-thousand-seven-hundred-and-fifty-five additional dollars are surely attributed to the RF’s sense of style. Love it or loathe it, the 2017 Mazda MX-5 Miata RF is a far more eye-catching car than the regular, fourth-generation MX-5.

Nevertheless, the MX-5 Retractable Fastback, which isn’t a fastback and doesn’t have a retractable roof, would be a distinctly more enticing proposition if it could save Miata buyers $2,755, rather than cost Miata buyers an additional $2,755.

Five years have passed since the Scion FR-S — known elsewhere as the Toyota GT86 and known now in America as the Toyota 86 (and at Subaru as the BRZ) — arrived in America. Buyers, never particularly numerous to begin with, are few and far between. Toyota now sells 62 percent fewer Toyota 86s in America than the Scion FR-S managed during its first year.

You expect to see sports cars peak early and then gradually fade. The degree to which the Toyota 86 née Scion FR-S has faded, however, has been more than a little striking. FR-S/86 sales have fallen so far, so fast, that U.S. car buyers are now ten times more likely to acquire a new Chevrolet Camaro, three times more likely to acquire a new Volkswagen Golf GTI, and twice as likely to acquire a new Mazda MX-5.

But is the Toyota 86 deserving of such rejection? Not according to a just-completed CAR Magazine comparison test in which the five-year-old Toyota claimed victory — ahead of the Mazda MX-5 RF and BMW 2 Series.

Let’s get right to it. Retractable hardtop MX-5 owners will pay a 113-pound penalty for their motorized, targa-topped fun. 113 pounds. Mazda engineers and marketers do not take that sum lightly. But we can, because unless you are stripping down your Miata for competitive track work — in which case you will select the softtop anyway — you will not feel the difference.

The hardtop does absolutely nothing to diminish the balanced, driver focused, analog pleasure of the fourth generation MX-5. And for the purists, consider your baby may one day only be visible in the rearview mirror if Mazda can not expand the audience for this little icon.

Mazda has kicked off presale orders for its 2017 MX-5 RF, the “retractable fastback” that gives would-be convertible buyers an extra feature to help win their spouse’s support.

Introduced to salivating journalists at the New York Auto Show, the model starts at $32,390 (including a $835 destination charge) in Club trim — a $2,955 increase over a 2016 MX-5 Club.
