Cars to move to different series?

NASCAR's rumored game plan for the 2007 car of the future is slowly becoming clearer. When the new, larger car is phased in in 2007, the current Nextel Cup cars would become Busch tour cars, and the current Busch cars (which have a smaller 105-inch wheelbase than the 110-inch Cup cars) will become part of a new Grand National series in Mexico, Canada, the Western U.S., and possibly England, according to NASCAR sources.
