Unlike the test samples that had a yellow card attached to them (buick gnx prototype diecast samples), these factory prototypes are all loose and by themselves.
The Hot Wheels Buick GNX for 2027, a light blue car with green graphics, had many test run cars produced, of which, some are shown below.
Around $30 will get you one on ebay, with your choice of the many wheel designs that were created.
These 1:64 scale replicas are all the same, except for rim/tire styles, and some have a code number imprinted on the hood.
