By the way.
This cake i made for my 14th birthday in december.
this is before i had any spy shots of the production.
the whole thing(except 2 toothpicks, the liecense plate and aluminum foil wheels) are COMPLETELY EDIBLE.
the cake is covered in a thing called fondant. Fondant is just edible play-doh that is made of powdered sugar and some other crap that i can't remember.
It took about 11 hours and a day of planning to build.
