I am making a convertible car cake and have purchased Mike McCarey's Cakenology dvd which is great! So I have most of the information down but I am stuck on one thing. My biggest problem is figuring out the size of the cake. I am making an infiniti G37 which needs to feed 50 people. On the dvd, Mike makes a Mustang and states that his cake is 17" long and serves approx. 30-35 ppl. So being that my car will be a convertible and I need to hollow out the cab (to put the seats in), I don't know how long/big my cake needs to be. (Does this make sense?) I was hoping someone would be able to help me in figuring out the size I have to make. I know this will be approximate being that it is a sculpted cake but I just need some direction.
Thanks for any help/tips you can share!
