Ok I'll bite:
IF Carroll Shelby did in fact sell the Trademark/name COBRA to FORD for $1.00 then ONLY cars manufactured prior to that sale by Shelby and Cars manufactured since that sale by FORD are Cobras. This would mean that the Mustang Cobra is a Cobra and the current Shelby look alike is not.
With apologies to all the cobras in India, Africa and southeast asia (who are really steamed that someone took their name)
