After making world debut in China, in April 2007, the Buick Riviera Concept will make its North American debut in a few weeks, at the Detroit Auto Show, which starts January 19, 2008. Even though there are no chances of ever seeing this car making into production, still it shows the direction Buick plans on going with future models, as rumors say the next generation Buick LaCrosse will borrow some elements from the concept.
