The association’s monthly market report for September shows a significant rise for both sectors, with the firm adding that it is likely that dealers are preparing themselves for this to happen again this year. By contrast, prices for convertibles have fallen from their seasonal highs and appear to be continuing a steady decline in value.

Paul Hill, Manheim regional director, commented: ‘The sustained retail demand bought good news for auction and trade activity, ensuring that there was a route to market for the increased supply of used cars that is normal for this time of year. As expected, contract hire and leasing de-fleet activity was in full flow once again following the summer season.

‘It is surprising to see a jump in premium 4×4 values, which have already remained strong through 2013. It is likely this is due to dealers actively buying stock ahead of the winter.’
