To be fair, Cadillac has fewer cars on offer than Mercedes, BMW, or Lexus. Still, GM wants to gets its dealer volume numbers closer that of the competition – proportionally speaking – and that means more dealer closings. GM hasn't said how many, but to even get close to retail parity they'd be looking at many hundreds of closures, with many of them likely to be in metropolitan areas. Whenever those dealers are chosen, as with the others, they will be allowed to remain open until their franchise agreements on October 31, 2010.
