The 2010 BMW X3 is a sport utility vehicle that places a lot of emphasis on sport. In fact, there are few other vehicles in this segment that feel as nimble and track-ready as the X3, while costing less than $40,000. With xDrive all-wheel drive, hill descent control and a cargo capacity of up to 71 cubic feet, the X3 is still able to capably fill the "utility" role. It's just that with its excellent inline-6-cylinder engine and great handling and sure-footedness, you may forget that's why you bought it in the first place.
