Mike Bowe - Wizard of Cov

Does anyone remember this character from the late 70s early 80s? He was the master of self promotion. I believe he was a car dealer (Datsun, DC Cook?) but no matter where you looked, he was right 'in your face'. My memories, are of him commentating (don't remember the station) on Coventry City, and of his face splashed all over the back of Coventry buses in a pantomime wizard get up.
