Would have been to expose a 'car API' to the user and provide an iPhone app using that API. I reckon stability and user experience must be important to Mercedes, so they could keep development in house to meet their quality requirements.
And: Maybe it's just me, but, Mercedes ads make bubbles of quality and conservative values appear in my head. Adding twitter and facebook integration to that, makes that bubbles burst right away.
