Homemade Tow Mater and Lightning McQueen Cake

I made this cars cake for my friends son. The cars are made out of pound cake and fondant. I also used some candies for the decorations. The bottom cake is just a rectangle cake with black and white buttercream piped into a flag design around the sides. I finished it off with a piston cup and 2 flags. It was a lot of fun to make.
