Chad, Color Shifters are pretty available at the typical places, ie. Target, Wal-Mart, etc. If you can't find one, let me know. When you pull the little tab on the right, the pic changes color on the package. I just got back from Italy and had one in my hand there. Front of the package looked the same, back had all sorts of other languages on it, including Italian. Didn't buy it as the car and front of the package looked the same as U.S. Only Viper I saw (toy or otherwise) in Italy, and believe me, I looked. Lots of Fiat, VW, Alfa Rameo, Lambo and of course, Ferrari.
CitySnake, I believe the 1:24 BigTime Muscle are 08/09 bodied. Hood vents certainly look like Gen IV to me. Package says 08, which of course, means nothing!
Jeff, A bigger RC one and an even larger yet 1:1 scale. So you painted the stripes silver on the RC car? Came with white, right? Mine did. Nice work!
