For $12B MSFT Could Buy Fiat Family (Chrysler, Ferrari, Maserati)

What could MSFT do with a car company?

I would make an electric vehicle better looking then the Volt, and more affordable then the Tesla,

Branded like this: "Introducing The Fiat S1, Powered by Cortana"

(The "S" in S1 stand for Surface, as in a roadster that hugs the road / surface of the earth.)

Have some fun with it. If you ran MSFT, and now owned those 4 car brands, what would you build?
