The average selling price of part exchange vehicles has risen for the first time since March, figures show.
Values were also 16.6% higher for the period of June 2012 to June 2013, according to data from Manheim's Market Analysis report.
The average of prices from the dealer sector increased by £37 last month, reflecting a fall of one month in average age and a fall in average mileage of 1,660 miles.
Selling prices have also seen an increase with a rise by £94 to £2,768 as an average selling price meaning buyers may have to shop around for better valuecar insurance .
This is despite a rise in average mileage of 317 miles.
Daren Wiseman, valuation services manager at Manheim Auctions, said: "The latest market analysis figures seem to show a fairly buoyant market, especially in comparison with the wider retail landscape.
"We're seeing dealers take a more flexible approach when it comes to selecting the vehicles they put out on their forecourts to attract interest but, inevitably, age and mileage still matter - especially in relation to the quality of the vehicle.
"And, while quality stock remains in short supply, we are likely to see average values continue to rise."
