Glass's Information Services reports that at nearly every auction venue over the past couple of months sales have been strong.
It adds that, at this time of year, less well-presented or even unpopular vans receive renewed interest due to the high seasonal demand for parcel movers.
George Alexander, chief editor, commercial vehicles at Glass's Information Services, said: 'In response to this, there is an accompanying short-term lift in their market worth. The trade's current buying confidence, as demonstrated at popular auction venues, virtually guarantees stable market conditions over the coming weeks.
'With the run-up to Christmas now firmly in our sights, it is reasonable to expect that this strong marketplace for the best light vans and pick-ups will continue at least into December.'
