Race Car Cake in the making.....

I'm working on the race car cake.  this one is giving me a run for my money.  I need to sculpt
it and it's not very easy.  My problem is that I want it to look very realistic.  Not sure if that's possible.  I will continue to work on it.  I was going to do all the accessories before hand, but I now know that some of these have to be done as you are decorating the cake.
Will be doing a video on it (of course!!)
