Mazda offered its popular MX-5 Miata roadster in two versions for 2004. Both the Base and LS versions were powered by a 1.8-liter four-cylinder engine that produced 142 horsepower. A five-speed manual transmission was standard for both models, while a four-speed automatic was optional.
In addition, in mid-year Mazda introduced the high-performance MAZDASPEED MX-5 Miata roadster, which received a turbocharged and intercooled 1.8-liter four-cylinder engine that pumped out 178 horsepower. The MAZDASPEED Miata also came with beefed-up springs and dampers, a modified double-wishbone suspension, and rack-and-pinion steering.
Standard features for the Base Miata included air conditioning, power windows, dual airbags, power exterior mirrors, and a CD player, as well as a convertible top. The LS version added leather seats, cruise control, and a premium audio system, among other features, while the MAZDASPEED Miata came with an upscale package that included black leather-trimmed upholstery, a black vinyl convertible top, 17-inch alloy wheels, and a Bose six-speaker audio system with CD.
Although drivers thought that the Miata's interior could be a bit cramped, that the ride could be a bit rough, and that the vehicle overall was a bit underpowered, they also felt the Miata had responsive handling, a smooth shifter, great styling, and overall was fun to drive.
