I know of two different Auto World exclusive, special edition slot cars that were sold by themselves (not in sets). The first one is a NHRA Top Fuel Dragster, MAV TV sponsored Brandon Bernstein. It is a chrome edition slot car and they only made 996 of them. The box states it is Release 11 despite the special yellow Auto World Exclusive sticker. This exclusive slot car shares the exact same sponsors as the regular Brandon Bernstein dragster from release 11, it just has a chrome finish to it instead of black. Check out the photos below.
