I think it came down to sales numbers. Buick was doing well throughout the crisis and the Regal especially. It is one of those models that has been around for years and will be a GM staple for years to come. Personally I can live without Pontiac or even Cadillac. I wouldn't buy either. The Buicks have always been a part of my family and I loved them from when I was a child. Pontiacs in recent history have been a bunch of crap minus the G8 IMO.
