New to Hot wheels or Real FX?

If you want to do anything fun, I suggest buying the Real FX Expansion pack from Amazon, about 40$ US. You get quite a bit of track, some U (left) turns, and some straights that will make for good racing.
  Unless you are limited in space, don't bother with the Crossover, I used it in several circuits and it didn't add anything, so I ditched it.I may separate it and use it for elevation changes but even then they are sharp bumps more than hills, and my hills cost about 2 dollars, there's are 35$, hmmm
