2006 BMW 530i

The 2006 BMW 530i four-door sedan was powered by an upgraded 3.0-liter inline-six engine with variable valve timing, which put out 255 horsepower. A six-speed manual transmission was standard, while a six-speed automatic overdrive transmission was optional. Standard features included such driver-assistance features as Hill Ascent Assist, Braking Assist, stability control, and traction control.

Beyond that, the 530i was equipped with an extensive list of interior and exterior features, including a one-touch power sunroof, multi-zone climate control, adaptive headlights, heated exterior mirrors, wood interior trim, a leather-wrapped steering wheel, power-adjustable front seats, cruise control, 17-inch alloy wheels, an anti-theft alarm system, a full range of airbags, and an AM/FM stereo system with a CD player.

In addition, the software for the iDrive navigation system - which got numerous complaints in previous years - seems to have been tweaked to make it "less annoying."
