The 2011 Hot Wheels Buzzerk with the orange plastic body has been found with and without the Hot Wheels logo on the rear of the car. From what I have with lot numbers, the Hot Wheels logo was taken off the the car. The lot numbers I have are C43 with the red Hot Wheels Logo on the tail and I have C45 without the Logo.
There is a color swing in the orange plastic body too. They range from light to dark. Also look at the saw blade…. they are both facing different directions, so keep and eye out for that too!
