Rain-sensing windshield wipers and automatic headlights became standard equipment. • IN 2005, options have been repackaged, the wood-trim option is a new hue, and the SMG is no longer available with the 2.5-liter engine. Electronic technology has gotten more advanced, with the addition of optional Sirius Satellite Radio, Bluetooth hands-free phone accessory, and BMW's iPod adapter, a dealer-installed item. The 2.5i model now has more standard equipment, such as foglights, heated side mirrors, and cruise control. Guess they didn't want to mess with a good thing--not even to give it the M package. |
