When the “F01″ 7-Series arrived in 2008 followed by the “F10″ 5-Series in 2009, I saw the writing on the wall; BMW is the new Mercedes. My theory was “proved” after a week with the 2011 335is and 2012 X5M. BMW fans decried my prophesy as blasphemy. I repeated my statement with the 2012 328i and caught the eye of egmCarTech. A Mercedes fan tried to run me over in a parking lot. My colleagues in the press thought I lost my mind. BMW’s media watchers were eerily silent. A month later I was told that BMW would allow me a week in the all-new 2012 M6 Convertible. Would the most expensive M car change my mind or prove the point once and for all?
