This was for my son's 5th birthday. My time was so limited when doing this, that I had to leave out some of the details. He immediately noticed that there wasn't a rear spoiler, but he still thought the cake was cool! I used a race car pan from sportscakes.com (no longer in business) which was kind of flat, so I made another sheet cake and cut out pieces from there to "build up" the original race car cake to make it shaped more like Lightning McQueen. It's all covered in MMF.
