Bah! I love the idea of the entire front opening... that way we'd also get to look at that monster of an engine that must be under the hood! And we'd be able to model our own add-on packs, like blowers ( with a corresponding transmap on the hood), turbo, chromed pipes, and so on! A simple chamfered box and a few tubes with texmap would be sufficient at first, with a morph to make it flat so we can put in our own motors should we so choose... now -THAT- would be awesome...

Remember, kids! Napalm is Nature's Toothpaste!
