MTL,
DO NOT BUY A CLONE !!! Unlike BC-Gs, where the clones at least resemble the original, the clone Mini-Zs are nothing like the real cars! Underneath the body they are unupgradable pieces of junk! Save your money and put it towards a real Mini-Z. If you are really set on buying a clone, I would suggest that you first go to Mini-ZRacer.com and post a thread "Are the Clones as Good as the Originals?" and see what people have to say.
