My friend Dennis from Australia gave me the Hot Wheels Year of the Goat 2015 car shown above left. I understand that it is exclusively available from Toys R Us. The Carbonic shown above right is a recent acquisition.
The Toys R Us version has part number CMD35-0710 3LW, while the other one has part number CFK61-07B3. While the cards are different, the actual cars seem to be exactly the same, except that the Toys R Us version has a G45 base code while the other one has a G42 base code.
