This is a beautiful car! It is the Cadillac Sixteen which is a V-16 GM Concept Vehicle. This is the first edtions series model that was released a decade ago in 2004. There are two first edition series colors, this is the silver/gray color. The plastic on this is discolored from time, the car is Mint/Unopened.  It is a great cross-collectible, so if you collect Hot Wheels, Concepts or Cadillac this is a great addition for your collection.
