The Mazda MX-5 Miata was available in four versions for 2003. In addition to the Base, LE, and SE (Special Edition) trim packages that had been available the previous year, Mazda added a new Shinsen version, which was a step up from the Base model but not as outfitted as the higher-end packages. The standard powerplant for all four versions was a 142-horsepower, 1.8-liter inline four-cylinder engine. A five-speed manual transmission was standard on the Base, Shinsen, and LS models, while a six-speed manual was standard on the SE version. A four-speed automatic was optional for all models. One of the few upgrades for 2003 was the addition of 16-inch wheels to all Miatas (up from 15-inch wheels the previous year). In addition, all models received larger brakes, while the LS version got a cloth instead of a vinyl top as standard equipment. Standard features across the line included air conditioning, power windows, dual airbags, and an audio system with a CD player. All models except the Base also received power door locks and cruise control, while the LS and SE versions were equipped with leather seats. The Miata's overall driving experience, or fun factor, was what seemed to attract drivers most to the popular roadster. As can probably be expected with a car this size, interior room could be cramped, and the ride could be a bit rough over long distances. On the flip side, drivers like the Miata's reliability, styling, build quality, handling, and value.
