One of the most important GM brands in China, Buick, is largely an also ran here in America with the exception of the gray haired citizens among us. This is especially true for those that previously would have, or could have, bought a Cadillac in better economic times or before Cadillac started making high-powered sport sedans. There does seem to be an infusion of life on the horizon with the Invicta Concept (see below), but in the interim the most exciting car for Buick is the LaCrosse.
