Twinmill in ice blue Spectraflame.  Designated in 1997 as the flagship car in the Hot Wheels line, due to it being the first original design released in the early days.  I don't remember the color of my first Twinmill, but the second one is aqua, near mint and still in my storage case.  This example is the second ice blue version I have recently owned, and this is the one in the display case.
