A replica of the Optimus Prime (movie version)truck is currently being sold on eBay. The working truck comes with a voice activated alarm, with the voice of Optimus Prime on lock and unlock mode, 17 inch LCD TV/DVD, a JVC JAVX33 Stereo CD/DVD player with Bluetooth and Satelite Radio ready, Infinity Sound system, speakers and subwoofer, and other goodies! Unfortunately, it can't transform to robot mode. Bidding ends in 13 hours.
