I started (as always) by googling "ambulance cake" and taking a look at what other people had made, my inspiration was this one
Here's my version:
|I made several chocolate sponge cakes and cut them to a basic shape||Then glued the layers together with chocolate buttercream and covered the entire cake in buttercream.||Then covered the cake in white icing - this bit was tricky, I did it in two parts the front cab and the back were 2 separate pieces of icing.|
Then I added window (cutting out the shape from the white icing and replacing with black icing), making the wheels and bumper (black icing) and then adding the rest of the ambulance logos:

I then added some blue lights, wing mirrors and a number plate JACK 18
Unfortunately I didn't get any pics of the back - which I did in the traditional chevron style (but it wasn't as neat as the front).
