Cox Automotive’s wholesale and retail brands saw a year-on-year increase in sold volumes in May, with selling prices up across wholesale and retail markets.
Daren Wiseman, head of valuations at Cox Automotive UK, said: “We saw strong selling prices in the wholesale and retail markets last month.
"From a Manheim perspective, this was driven by a shift in stock profile, with a higher proportion of higher value, ex-fleet cars sold in May.
"With continuing focus on diesel, the strength in demand shown for diesel cars in the wholesale market is an important observation for the market.
“Although we saw prices rise in May, some vendors were not adjusting reserves in line with the market.
"We continued to see high stock levels across the auction network last month, which meant that it was largely a buyer’s market.”
