As Anne pointed out before, you can order your own R2D2 robot.
But if you are really R2D2-obsessed how about owning the Rolls-Royce that once belonged to the actor who played the role of R2D2. Kenny Baker, the small actor who played the robot in all six "Star Wars" movies owned the car from 2002 until recently. The blue Rolls-Royce is a 1982 Corniche Mulliner Park Ward Coupé with around 63,000 miles on the odometer. It is expected to bring in between £11,000 and £13,000.
