I now have a dozen Carrera GO cars and am very happy with it. Of course you can not go anywhere with all the cars at full throttle - this they are also not there and that would certainly be boring. The attention to detail to the original is impressive - the prices (if bid) at Amazon are unbeatable. I have already flown several cars from table height off track - on tiles, mind you - and yet they have remained undamaged. Of course, at some point end with is "durable" in continuous crash, one can hardly blame them. Anyway, a hobby of Father & Son, which makes us much joy.
