Average used diesel prices of cars sold on the Autorola online portal continued to rise in Q2, although there was a noticeable fall in volume.
Diesel prices rose £681 (6.1%) in Q2 to £11,839, helped by a fall in average age from 34 to 33 months and a fall in average mileage from 30,323 in Q1 to 26,112 miles.
Used volumes fell 9.8% which may have also contributed to the price increase.
Jon Mitchell, group sales director of Autorola UK, said: “The used market is still in rude health across all sectors. Diesel prices keep defying the market and continue to rise, while the supply and price of used petrols has never been higher."
Average petrol prices rose for the second successive quarter to £9,204, an increase of £226 (2.5%) despite a rise in average age from 31 to 32 months.
Petrol volumes grew for the third successive quarter by 12.8%, to a three-year high, reinforcing that the churn of petrol cars in the used market is continuing to rise.
The supply of hybrid and electric cars was minimal in Q2 with only a handful of ex-demonstrators hitting the Autorola portal at an average age of seven months and 3,000 miles. The average price of cars sold was £20,133.
Looking forward to next month, Mitchell added: “August may cool the market down after this long hot spell, but it looks unlikely prices will change dramatically over the coming months.”
