Used car values have crept up for four months in a row due to a scarcity of quality used stock in the wholesale, auction and retail markets, according to HPI.

HPI believes dealers have been left short of stock and therefore are able to command values slightly above the usual levels for June.

Compared with May, used car values in June show a small increase for the fourth month in a row, with 12 month old cars up by 0.2% while 36 month cars are up by slightly more at 0.9%.

Petrol cars that are 36 months old fared best with values up 1.4%, compared to diesel up 0.4%. Meanwhile petrol vehicles 12 months old were up in value by 0.6%, while diesel had a negligible increase of 0.2%.

The overall year on year rate of depreciation has slowed down for the second month in a row, from 18.5% to 15.6% with all sectors continuing to perform well.

The depreciation in all 12 month cars has improved slightly from -16.6% to -13.6%, while 36 month cars saw a drop in depreciation from -22.5% to -19.8%.

Diesel had a better month than petrol for the first time ever with 12 month diesels faring the best with a decrease in depreciation of 3.6% to -12.9%. Meanwhile the 12 month petrol sector saw a drop of 2.2% to -14.4%. Both 36 month petrol and diesel cars saw depreciation drop by 2.8% to -21% and -18.6% respectively.

Martin Keighley, HPI’s used car valuations expert, said: “The used car market has shown signs of much needed stability in June, with many trends continuing on from last month.

“The used wholesale market remains relatively buoyant; however prices have continued to even out to a point where the market has nearly levelled. The prices we see now are still on a par with last September. Small cars and superminis with low mileage are continuing to get good prices at auction, but higher mileage and larger cars struggle to find buyers, and retail activity remains patchy. Month on month rises will slow or stall over the coming months, but year on year values will keep improving.”

Keighley is expecting the summer period to be dominated by uncertainty and recommends a cautious approach to any notion of the green shoots of recovery.
