Sometimes you can find a model of your car that someone has done for free. If not you can usually buy a 3D model of your car.
Unfortunately Blender will (as far as I can tell) only show you smoke flow around an object. Not give you numbers for things like drag. Still it might give insight on some things like air dams and boat tails.
I wouldn't expect it be able to tell you how to install vortex generators as even the professional CFD programs have trouble doing that without a real wind tunnel to verify assumptions.
