Mercedes-Benz's new compact C-class estate will make its world premiere at the North American International Auto Show in Detroit next month. The new estate supersedes the current C-class wagon, about 250,000 of which have been produced since spring 1996. Approximately one third of C-class customers have opted for the estate but that percentage is likely to increase when, from September 2001, Mercedes-Benz offers the wagon to US customers for the first time.
