I am not sure what size cakes to make. The car is pretty boxy, client isn't overly picky about every little detail. I need to it be right though because for the first time I charged a decent amount for a 3D cake.

I was thinking about a 10x15 cut in half and then a 6" square on top and carve it down. What do ya'll think?

Any suggestions?

TIA!

I'm bumping this up. Sorry, I really need some input on what size cake to bake. Thank you.

That should be fine, that gives about 35-40 servings cut down to 30.....

Thank you for taking the time to reply!
I'll do just that.
