EVERY cloud has a silver lining - but not in the used car market where silver overkill is threatening to reduce the future values of cars chosen in today's most fashionable colour by up to £500. CAP Motor Research says this week that an analysis of colours of manufacturer models sold showed that up to 40% of some lines were being bought new in silver. While silver is particularly popular with prestige brands, it is also now proving a favourite with buyers of the 'bread and butter' family car.

Previously, on some top brands a silver car could command a premium of £300 in the used market, says Mark Norman, editor of CAP's 'Monitor - Future Residual Values. However, its increasing popularity could mean not only the premium disappearing but could bring a further reduction of about £200 in residual value, potentially costing fleets about £500.

He adds: 'Silver looks superb on new cars, especially as most are displayed inside showrooms with lighting designed to show them to their best advantage. However, standing outside with a few years' wear and tear, the same cars tend to look much less appealing. Fleet managers should not over-expose their fleet to any one particular colour. Fashions can change.'
