I'm not sure that I'm a Buick champion quite yet. I think there are other brands that are doing a lot more than Buick in order to increase their appeal, and I'm still of the opinion that the Regal GS was/is the only car in the Buick line-up that I would consider owning since I was looking for something more aggressive and sportier-looking than their other cars. I believe I mentioned this either in my show n shine thread or my thread in the buying, selling and leasing section.
Buick would have to get more cars in their line-up that appeal to me before I could recommend the brand to other people (and be a true brand champion!) my age. I cannot afford a 45-50k car and neither can most people I know. The only reason I own a Regal GS is because of the deal I got on it. Making the Verano Turbo better looking and bringing the Opel Cascadia to NA would also be steps in the right direction imo.
My friends (including Sir O) will tell you that I continue to make Buick jokes, and still can't believe I bought one. Brand image can be a powerful thing. If I could afford it and it was two months ago (and I had to pick between the Regal GS and ATS performance pack), I probably would have bought the ATS with the performance package, assuming the test drive went ok of course.
