Oddly enough, Buick makes some darn good cars. Don't they have like the highest JD Powers #s of any car sold? Higher than Lexus? If I'm wrong someone can correct me, but I seem to recall this.
I've considered a used one for a daily driver, granted they're not exiting but I like American cars for *appliance* duty. Used Buicks are dirt cheap and the 3800 engine is fantastic delivering high 20s mpg in a big luxury car.
I would think that Buick would be a big piece in the puzzle of saving the domestic auto industry.
