Cost of BMW M Performance Aerodynamic Kit?

First post here, so be gentle....

I'm currently looking at getting myself my first bimmer, but most of them are part of the other lines apart from M Sport, like Sport Line, Luxury Line and Modern Line.

Now the external feel of the other lines are too mundane for me, so I would want to get a M Aerodynamics Kit for my car to improve visual appeal.

Does anyone know the cost of the BMW M Aerodynamics Kit for the 3 Series? I phoned around to get a price, but no one has come back to me yet, so there goes that idea.



If you are wondering why I don't get a M Sport model, $$$ is the issue, so is mileage...

Thanks for viewing!
