I think this is probably my most rare item... Chase Bling Bling McQueen with The King Piston Cup... as far as I know, it's the only one that's been reported...



Close-up:


Another rare item I have is this from an Amazon Black Friday purchase a few years ago:


I knew Mater could drive backwards... I didn't know he could drive upside down.

Other rare items in my collection include the Gask-Its French Promo Car (supposedly only 200 released), Chase Mini (Mini on a Chase Mario Andretti cardback), 2 Cars Cares customs which are each 1 of 10, and my Speedway of the South set...
