“Uptown.” The phrase conjures images of sophisticated luxury – timeless elegance with a flavor for the avant-garde. It is fine furnishings and the latest electronics, cool jazz with an equal dose of hot salsa. It’s the blending of two colors to create a distinctive new shade. That’s the premise behind the Buick Enclave UpTown being introduced at the 2007 Specialty Equipment Market Association Show in Las Vegas. It was created by Rick Bottom Designs of Mendota, Ill.
