Hi All can I get some of your suggestions on how you would make this cake? I just need about 40 serves. I am thinking in lines of a 9X13 inch cake pans. Modelling chocolate for the handles and back. Semi circle foam ball (cut in half) for the white dome under the handle. 

Would like to get some ideas from you all.

Thanks heaps

ASounds good to me. I would use cake for all the parts but the handles. Modeling chocolate / fondant is a good idea...with some skewers to hold them in place. If you have the vehicle at home it'll be even easier for you to get the proportions right...
