High Quality Content by WIKIPEDIA articles! The Buick Terraza is a minivan from General Motors` Buick brand that was sold from the 2005 through 2007 model years. It filled the position of GM`s luxury minivan that was previously occupied by the Oldsmobile Silhouette until the division`s demise in 2004. The Terraza was built alongside its Chevrolet, Pontiac, and Saturn sisters; (Uplander, Montana SV6, and Relay) in Doraville, Georgia. Contrary to popular belief, the Terraza was not Buick`s first minivan – the GL8 debuted in China in 2000, where it was solely marketed and is still produced and sold today.
