A spokesman for Chrysler Jeep, said: 'We are having a sales drive within the auction network to show to the valuation experts the prices that our cars can achieve. This method of showing how our vehicles are in demand will drive up residual values in the guides. We cut prices last year and even so our used values have been increasing.'
Tony Styles, an editor of CAP Black Book, said: 'It was a closed sale, and some of the dealers had already pre-sold vehicles, so they were able to pay strong money. However, residual values for the manufacturer's product are being marked up, with Voyager and Jeep Cherokee diesels up about £200.'
