Mazda offers Sport, Touring and Grand Touring trim levels for both four-cylinder and V-6 sedans, with increasing levels of equipment in each. There's also a budget-minded SV four-cylinder trim level that includes standard 16-inch steel wheels, air conditioning with a pollen filter, a tilt/telescoping steering wheel and a CD stereo with steering-wheel controls.

Sport models add cruise control, remote keyless entry and an auxiliary input jack for playing a portable music player through the audio system. When powered by the V-6 engine, Sport models also get 17-inch alloy wheels.

The midrange Touring gains 17-inch alloy wheels, fog lights, electroluminescent gauges, a leather-wrapped steering wheel and shifter, push-button ignition, a trip computer, a power-adjustable driver's seat and an alarm system. With the V-6, 18-inch alloy rims and tires replace the 17 inchers.

The top-of-the-line Grand Touring gets automatic xenon headlights, LED taillights, heated and dimming outside mirrors, rain-sensing windshield wipers, the blind-spot warning system, automatic dual-zone air conditioning, heated leather front seats with a driver's-side memory feature, a power passenger seat, and Bluetooth cell phone connectivity. Choosing the V-6 brings 18-inch alloy wheels, too.

A touch-screen navigation system for the Grand Touring trim is a stand-alone option, and the Moonroof and Bose package for Touring and Grand Touring models includes a moonroof, Sirius Satellite Radio and a six-CD Bose audio system.
