As of 2006, the xB wagon accounted for 40% of Scion sales in the United States.  Its look, unique when it debuted, has since found its way into competing brands, but the Scion is still unique in its offering of 40 different accessories that the driver can choose at the dealership to customize their ride, and all at an economy price.

The 2006 xB shares its engine with the xA -- a 103-hp, 1.5-liter I4, with choice of 5-speed manual or 4-speed automatic transmission.  It has been called the most fuel efficient car on the market right now.  The EPA estimate is 30/33, but some drivers have reported close to 40 mpg.

Only one trim level is available for the xB. Its square-shaped box style adds extra interior headroom, and makes it a good buddy hauler.  A lower suspension improves the ride, and ground effects give it a tuner look.   It also has the same standard equipment as the xA, with power windows and locks, ABS brakes, air conditioning, tilt steering wheel, and a powerful new Pioneer sound system with iPod connection and a screen that displays artist and song information.  Also new is turn signals integrated in the mirrors.

Options are abundant, and include front and side airbags and a host of add-ons that help you create the exact car you want.  Whether it's a rear spoiler, leather trim, special lighting setups (lit cupholders!), or an upgraded sound system, the 2006 xB has 40 options from which to choose.  

Drivers are pleased with the xB's handling, but the firm suspension can lead discomfort on long trips.  The compact MPV also earns accolades for roominess, high seat height and visibility, sound system, and fuel economy.   The budget price, combined with Toyota quality also has great appeal.  The noisy and underpowered engine is a drawback.
