I could consider myself Buicks target buyer, i'm under 40 and my last car was a Lexus. I drive a ton of freeway miles each year, i look for a comfortable car that above all is smooth and quiet. The Buick has managed to impress me on all fronts, a very solid car that has remained that way after 45k miles. It makes me feel good driving a American car again.
Stylish on the outside, and the interior gives up nothing to the import competition, the way it drives and feels, a great car all in all.
Blind spots are a problem, i got used to it rather quickly, fuel economy could be better.
