Class leading residual values have been predicted by CAP Monitor for the new Mazda6 that goes on sale in the UK next month. CAP Monitor has predicted a best in sector residual value of 35%, based on three years and 60,000 miles. This compares well with the rival new Vauxhall (Opel) Vectra at 32% and VW's Passat (32%) and is way ahead of the dull looking and driving 626 predecessor. In contrast, the 6 has attracted excellent early reviews in the UK motoring press.
