Mark McNabb, North America vice president, Cadillac/Premium Channel, was a rolling stone, wherever he left his hat was his home.
After twenty years with Nissan, Mr. McNabb has decided to embark on a rollercoaster ride of a career.
McNabb left Nissan, went to Mercedes-Benz for a brief stint and then headed back to Nissan in 2007.
Less than twelve months after that, McNabb left Nissan once again for Cadillac.
Now just 13 months later he has hit the eject button at Cadillac.
As Chef from South Park would say, "What the what?"
