All 3-Series are well equipped. Notable standard equipment on the base 328i includes leatherette upholstery, dual-zone automatic climate control, HD radio and run-flat tires with 16-inch wheels on sedans and wagons and 17s on coupes and convertibles. Coupes also come standard with a sport suspension. Moving up to the 335i adds driver's seat memory, adaptive headlights, a sunroof for coupes and sedans, and leather upholstery for the convertible.
The new 335is, which is offered as a coupe and convertible, adds equipment otherwise offered only in the M Sport package, including the M Sport steering wheel, M Sport seats, an anthracite headliner, 18-inch wheels and stiffer engine mounts. The 335is also has a slightly modified look front and rear.
The M3 comes with a limited-slip differential, larger brakes, performance suspension and staggered 18-inch tires. The M3 coupe also has a carbon-fiber roof.
All 3-Series iterations come with a full slate of safety features, including dual front airbags, front side airbags, anti-lock brakes, a tire-pressure monitor, traction control and electronic stability control. All but the convertible also have side curtain airbags, while the convertible has automatic pop-up roll bars. Manual-transmission versions also get a hill-holder clutch.
