Those of you waiting on the DTS/STS replacement had better have a seat. Your new big-body Caddy will be ready in two and a half years. The National Post is reporting that Cadillac’s new XTS will be assembled in Canada’s Oshawa, Ontario plant. This is a big win for the factory already producing the current Chevrolet Camaro in addition to the upcoming Buick Regal and Chevy Impala. No further details about the car were provided, but production is slated to begin December of 2011.
