Mazda is adding a bit of extra mojo to the MX-5 Miata at the Chicago auto show, debuting a limited-run variant with a hardtop and contrasting trim.

The special-edition model starts at $32,020 when equipped with the six-speed manual, and $32,470 for the six-speed-automatic-transmission model. The cars will arrive in showrooms at the end of this month, and Mazda will make 450 copies.

The special edition gets black outside mirrors, body-colored door handles and black trim for the grille surrounds and fog lamps. The exterior comes in red or white. It all rolls on 17-inch aluminum-alloy wheels. The cabin gets black upholstery and piano-black panels for the steering-wheel spokes and instrument panel.

Power comes from a 2.0-liter four-cylinder rated at 167 hp with the manual, 158 hp for the automatic.
