The newly-enlarged Mercedes-Benz sales department incorporates both retailer operations and corporate sales teams. The changes take effect at the beginning of September. Pat Cambage, National Corporate Sales Manager for Mercedes-Benz and smart, and Brian Luff, Leasing and Rental Manager, will report to Simon Oldfield in his new role. The changes were explained by Dermot Kelly, Managing Director Mercedes Car Group: "As our business continues to expand, the time was right to enlarge our National Sales department, and enhance our Marketing operation … Following the Corporate Sales Department's restructuring back in November 2001, we've had two years of great success in this important sector of our business. As we move into a new stage of growth and development in our corporate operations, it is vital that the work of our national key account team is fully integrated with that of our expanded retailers' corporate teams."
