Skip the $2,000 navigation system, and you’ll get regular controls for the stereo and climate systems instead of a fussy iDrive controller in the center console. That’s great news for the 2006 BMW 3 Series, along with added space and new features designed to make trips more comfortable.

Our Sport models were equipped with multi-adjustable sport seats up front, manual on the 325 and power on the 330. With new inflatable side bolsters; thigh bolster extensions; and fine adjustment for rake, angle, and height, these seats conform to just about anyone, and once they’re set properly, prove comfortable and supportive, if a bit restrictive, over the long haul.

Despite gains in interior room, the 2006 BMW 3 Series is still an intimate car. It’s difficult to get into and out of due to small front door openings and an intrusive rear wheel well, and once situated inside the cabin snugly envelops its occupants. Legroom in front is quite generous, and four six-footers can comfortably ride in the 2006 3 Series, provided the driver and front passenger aren’t performing a gangsta lean. With the driver’s seat adjusted for a six-foot-tall person who likes to sit up nice and high with a good view forward, another six-footer can slide into the back and enjoy enough legroom that knees and shins clear the hard front seatbacks.

Passengers riding in the rear seat of the 2006 BMW 3 Series get rear air vents, power points, and a fold-down center armrest. Both front seatbacks are equipped with storage nets, and a power rear sunshade is available to cut solar glare and heating.

Note that BMW has improved its optional leather upholstery to the point where it is officially easy to tell the difference between real cowhides and the standard leatherette. The leatherette is rather stiff and grips clothing, making it hard to adjust your body while underway. In contrast, the leather is soft and smooth.
