The Bottom Line: The 2008 Volvo S80 is one of the more comfortable cars we've tested, and gets good mileage for a car of its size. Cabin tech doesn't go out of its way to work with personal electronics, but the safety gear is cutting edge.

The Bottom Line: The 2008 BMW 535i is a really exceptional car, offering a great driving experience and an impressive array of electronics in the cabin. From its shifter to its live traffic system, its innovative features should make any techie drool.

The Bottom Line: We found the 2007 BMW 328xi more at home driving twisty mountain roads than mall parking lots. Its interior quality may tempt drivers looking for a luxury ride, but only sport drivers should consider this car.
