Materials used inside the xD are generally good for a car in this price range. The expansive plastic that covers the dash and door panels has a woven-grain, matte finish, and it's more appealing than the glossy hard stuff in some inexpensive cars. The shiny black plastic trim pieces look like piano lacquer, and better than fake wood or metal.

The seats are covered in dark charcoal fabric and are quite handsome, especially when compared to the cloth that comes with some other cars in this class. The upholstery isn't plush, but it feels sturdy. The front seats are firm but not too firm, and provide decent bolstering, which is good because many xD owners will be ripping around corners after they add Toyota Racing Development suspension components.

Switches are well placed, with the audio system above the air conditioning controls in the center stack. All the knobs are big and easy to find, though those for the climate controls have a slightly loose, jerky feel.

The gauges are mixed bag. The primary display, which Scion calls a concentric combination meter, is a speedometer and tachometer in one package, centered over the adjustable steering column. It's designed to be different, but in this case it's not better. With the tachometer and speedometer needles moving in opposite directions around a circle, it's hard to process the information at a glance. The gas gauge is a bright, easy-to-read LED to the left of the steering column, and the xD comes standard with a multi-information display that allows the driver to toggle between the odometer, trip meters, instant fuel economy, average fuel economy, distance-to-empty and average vehicle speed. Not long ago, such trip computers were reserved for luxury cars.

The 160-watt Pioneer sound system with six speakers is loud and clear, and plenty for a car this size. Dealer-installed upgrades are available for buyers who want more. The standard system is wired for iPod, MP3/WMA, and satellite, and includes an auxiliary input jack. Like the trip computer, the redundant audio controls on the steering wheel spoke are the exception in this class.

Somehow, despite gaining three inches in wheelbase, the Scion xD has less interior space than the xA model it replaces. It's lost one inch of legroom in front, and passenger volume overall has decreased, from 86.0 cubic feet to 84.5.

The xD's rear seat is quite roomy when rear-passenger space is maximized. The rear seat easily slides forward or backward six inches, adding space for either cargo behind the seatback or passengers in front of it. With the rear seat moved full forward, there's enough legroom for a 12-year old; with the rear seat moved back, there's room for medium-sized adults. Head room is expansive, and with the front seat set for a 5-foot, 10-inch driver, there was enough rear legroom for a 5-foot, 9-inch rear passenger. Moreover, the rear seatback reclines 10 degrees, which remains a rarity in all cars. The rear-seat headrests rise a long way from the seatback, allowing more comfort for passengers when the seat is occupied, and better rearward visibility for the driver when the seat is empty.

Cargo volume is good, which is important if it's stuff you carry more than passengers. The rear seat folds totally flat, opening 35.7 cubic feet of space behind the front seats. That's less than the Honda Fit (41.9 cubic feet) and substantially less than the Nissan Versa hatchback (50.4). Small compartments under the xD's cargo floor hold the jack tools and leave some extra room, though not
