Thanks to increased dimensions, the 2006 Mazda MX-5 Miata's cabin can accommodate taller and wider people in greater comfort. Hip, leg, and shoulder room are all improved, and there's more seat track travel than before. Mazda has also included an adjustable steering wheel to help bigger drivers find an optimal driving position.

Not only is the 2006 Mazda MX-5 Miata's cabin larger, it gets additional storage space for improved daily-driving utility. The glovebox is bigger, the door panels have bottle holders molded right in, and the rear bulkhead includes three storage compartments (two located behind the front seatbacks). Two cupholders are also located in the center console, and a coinholder is a new feature. The trunk is larger, too, though still adequate only for weekend getaways for two.

Simple, modern, and punctuated by signature round air vents, the 2006 Mazda MX-5 Miata's dashboard continues a traditional design theme. The center dashboard panel includes intuitive knobs and buttons for the stereo and climate controls, and the MX-5 Miata's five analog gauges feature metallic trim and polarized glass to reduce glare in bright sunlight.

Manually operated like before, the top drops to fit flush and smooth with the 2006 Mazda MX-5 Miata's body, eliminating the need for a snap-on tonneau cover. The top includes a glass rear window with a defogger, and a detachable hardtop is optional for both foul-weather climates and to meet amateur racing regulations. Black is the standard top color, with saddle (tan) available on upper trim levels.

Three interior color schemes, each matched to the piano black trim and silver control accents, complement the eight exterior colors. Base 2006 Mazda MX-5 Miatas have black cloth seats, while higher-grade models are equipped with a choice between monotone black leather or a black-and-saddle leather treatment.
