I made this in Google Sketchup in 4 hours. It's still far from done and I don't usually make vehicle models, but I decided to give it a go and made this up.
It's just some random design I made up...
It's kinda sucky because I don't have Sketchup PRO so I can't export a 3DS so I can do a clay render in Blender...this is as good as i'm gonna get it right now
the wireframe of it can be found on my DA account
