Could the MX-5 get any better? You bet, as Mazda pops a slick new roof on its popular convertible.

Mazda wanted to make the 2007 MX-5 Miata retractable hardtop more of a 50-state, all-weather car. The sleek, no-fuss lid makes sense particularly in sunny California.

It takes 12 seconds to raise and lower the top. Trunk space (5.1 cubic feet) is unchanged from the canvas-top model.

With the top stowed, the MX-5 looks like it never had one. Road noise is comparable to a closed cockpit car.
