"As the Iraq war continues to send wounded soldiers back to America, Toyota's Scion youth division has created a version of its boxy xB hatchback to sell to disabled veterans.

Scion has paired with aftermarket manufacturer Indpendent Mobility Systems Inc. of Farmington NM, to create 20 units a month of the Scion xB xRamp.

The modifications include removing the rear seats and installing a driver's seat, power rear door, and power ramp."
