he 2004 BMW X3 is an all-new, mid-level, near-luxury sport-utility powered by the company's proven six-cylinder engines.The X3 is equipped with BMW's xDrive all-wheel-drive system, Dynamic Stability Control and Hill Descent Control, all designed to give it tenacious grip and secure control in less than favorable conditions. BMW may build the ultimate driving machine, but the X3 shouldn't be considered a contender for the title of ultimate off-road vehicle.This isn't BMW's intent.But the X3 should do what a BMW owner feeling the need for something akin to an SUV wants as well as or better than any other in its class does.And this it does. The X3 is quick and fast, considering its heft.The xDrive puts it at the head of the class when weather or road goes north.It's roomy, both for passengers and cargo.And just as important, it's replete with safety features, both active and passive.
