The 2007 Mazda MAZDA3 is a reliable and sporty compact car. It comes in two body styles: a four-door sedan and a five-door hatchback. Customers can choose from three trims: the base i and the higher-tier s, both available in Touring or Grand Touring trims. Engine options include a 148-horsepower 2.0L four-cylinder for the base i trim or a more potent 156-hp 2.3L four-cylinder for the s trim. A five-speed manual gearbox comes standard, with an optional four-speed automatic for the i trim and a five-speed for the s. Its features include a six-speaker stereo, air conditioning, full power accessories, key-less entry, and cruise control. Higher trims offer more upscale amenities like leather upholstery, a moonroof, a Bose sound system, and heated seats. Notable safety features include front-seat side airbags, full-length curtain-type airbags, antilock brakes, and stability control on certain models.
