The corporate spin on this being a positive is hollow. Buick dealerships disappearing may be good for those remaining dealerships in the short run, but not for the Buick brand. They won't sell more cars with less dealerships.
I took a look at both the Buick and Chevy lineup of SUVs and Crossovers and I wouldn't know one from the other if I saw one on the street. Same goes for most any brand right now.
