Transformer default robot body

[mbaki]

I am looking to download a 3d max model of the default transformer robot body for a personal project. Preferably the default robot body of an autobot like bumblebee. I will then take it into 3dmax and add my own armor and vehicle parts to it. Could some one recommend where I can find such a 3d max model. Here is the vehicle I am going to make the transformer have parts of. While he might have an autobot default robot body he is going to be a decepticon.
