In addition to this operational show truck, TRD and the Toyota Technical Center (TTC) engineers also built a blue-duct-tape-and-aluminum mule with the same engine, but sporting further chassis, steering and aero-dynamic refinements to make an even more brutish track destroyer.
My info comes from 20 years working with TRD and it's workers who's names will not be listed. As a note car makers don't sell their test cars.
F.Y.I. TRD/USA is now run by Toyota/USA
1- show truck
2- blue duct tape
3- and a blue base model
3. blue base model... that's just that a base model XRunner, nothing special about that one. So there was still only 2 truck used for development (whether or not they had a stock truck lined up for further testing).
the truck's had no VIN, so it would have been illegal to sell...
Aside from C&Ping snippets from that article i'm not sure what your trying to argue....
