USED values for many luxury cars have fallen, Glass's Information Services has claimed.

The company says models such as the BMW 7-series and Mercedes-Benz S-class are losing out to large prestige 4x4s like the BMW X5 and Volvo XC90 and prestige saloons such as the BMW 5-series and Mercedes-Benz E-class.

Richard Crosthwaite, specialist car editor at Glass's Information Services, said: 'The launch of several new luxury models, the widespread availability of discounts and incentives and more new diesel options have prevented further significant falls in registrations, but this still counts as a poor performance against a backdrop of record year-on-year sales across the UK car market as a whole.'
