I agree - to own a nice minty one with the box etc would be great.... although to be honest there's very little difference between the Worlds & your old Team Car, some milled slots in the chassis, some graphite shock towers & a carbon fibre tranmission brace!
I do own a Worlds car, but it was re-built/restored from a very rough car I found on ebay. I re-built it to be a runner with 2.2" wheels & a B4 slipper assembly (better for handling the torque of modern brushless motors) I've raced it a few times & it goes very well!
