The base model 328i sedan of the 2007 BMW 3-series comes with a 3.0 liter, 230 horsepower, 6-cylinder engine with electronic throttle control, and a six-speed manual transmission. Its smooth ride is provided by a "Dynamic Stability Control" system that includes a start-off assistant, brake fade compensation, a brake stand-by feature, and dynamic traction control. As well, much of suspension components are constructed from forged aluminum, and there are front and rear anti-roll bars, in addition to variable-assist power steering that is engine-speed sensitive. The 335 series has a similar engine, but 300 horsepower, while the 325 convertible sacrifices sturdiness for style, and offers a 184 hp engine.

In addition to the braking systems mentioned above, the safety features of the 3-series vehicles include front SRS airbags for the driver and front passengers, with a sensor for the passenger seat, and front side-impact airbags as well. Safety features also include a front and rear head protection system, a crash sensor that engages lights, and unlocks the doors, a LATCH child-seat system, and programmable daytime running lights.

The interior of the 3-series cars are brim-full of comfort and convenience features, like a 10-speaker AM/FM radio CD/MP3 player audio system that is set for a Sirius satellite radio and a6-disc changer, a computerized "check control" system that gives constant information on fluid and fuel levels, among other settings, and an engine start/stop button. As well, there are power doors and windows, a power moon roof, and center consoles in the front and rear (front console has cooled storage, back has cup holders), and air cooling control that includes a fog-proof windshield.

All this and the smooth ride BMW is known for make the 3-series automobiles an excellent choice for the discerning driver.
