The xD has a fairly long wheelbase for its overall size, which should contribute to a smooth ride and good interior space, and the short overhangs help with maneuverability in tight spots.  

The xD roofline is boxed in at the rear corner with a wide C-pillar, and its hood is long and quite bulbous.   The halogen headlights are sleek, but they're pinched in a shape at odds with the roundness of the hood, which has a chrome Scion emblem stuck on the front.  

The standard steel wheels measure 16 inches in diameter, and the wheelwell gaps have been tightened, which is good.   But none of the three wheelcover styles do much for the car.   A sharp set of wheels goes a long way toward bringing the xD alive, and that's part of Scion's personalization platform.   We've seen xDs with the six-spoke, 18-inch polished alloy wheels available from Scion dealerships, and they totally change the bulky looks of the car.   The 17-inch black alloys look great too, and those who don't want to spring for new tires can choose 16-inch alloys.   With wheels and a rear spoiler to extend the lines of the roof, the xD looks more like something worth showing off.
