3D Classic Lightning McQueen Cake

This cake was a stressful one :) I woke up in the morning before the cake was due and realised I had completely forgotten about it. From baking to delivery - this cake took me a total of 6 and half hours :D it's a record for me lol. The cake was a chocolate mud cake filled with caramel buttercream and was covered in marshmallow fondant. All decorations were edible.
