I just checked "hotwheelscollectors.com" and it appears the next model to hit the shelves will be a red version. I will try to attach the link. Just scroll thru the HWC Sneak Peaks at the bottom right. http://www.hotwheelscollectors.com/ Kevin 70 GS Clone (and avid Hot Wheel collector)
"The flashy ’70 GSX™ package got buyers a four-speed tranny with Hurst shifter, mag wheels, disc brakes, and heavy duty cooling – but it cost almost 40% more than the base GS455 coupe! Our recolor will rock your world for a whole lot less when it arrives in Mix K." Hot Wheels"
Those are very nice quality models, cost about 12-15.00 each if I remember right (I have a red one still in package)and came in their own plastic case. I wish hot wheels would make a 71 or 72 version of the current GSX, easy to do...on the latest round of cars, all they would need is to mold a new plastic base, the bodies, interior and clear parts could be exactly the same.
