Buick Confirms New Models, Targets "Customers that Shop at Ikea and Drink Coffee at Starbucks" - Carscoop
Maybe they target this sort of costumers because with some much caffeine in their veins they won't fall asleep when they drive their Buicks or something.
Also, in a related note it's funny to see Americans (well, if I'm honest Autoblog mainly) so excited with what basically is an Opel with an automatic and a four cylinder engine.
