Futuristic Auto

I like to create inorganic and organic modeling my goal here is to create a futuristic police vehicle from a current vehicle type in this case a Subaru Impreza WRX-ST used in Japan, I have taken the current blueprints and will create an idea of what this vehicle might look like in 5 to10 years in the future. The current model half is a minuscule 414 polys, that will be mirrored or completed by the symmetry modifier, my goal for the completion of this model is 1500-2000 polys or less. These cars could literally litter the screen and through animations scenarios be set-up for multiple crash and chase scenarios.
