Used car transactions rose by 5.9% in the second quarter of 2016 compared to the same period last year.
A total of 2,008,439 vehicles were sold with prices underpinned by strong consumer demand.
The performance over the quarter was strong despite a sharp decline in activity in June volumes which rose just 0.5% to 632,449 vehicles.
Philip Nothard, consumer and retail specialist at cap hpi said: “Despite large volumes of used vehicles available the market has remained steady through 2016, with the market following seasonal trends.
“And while June saw a sharp decline in activity, it should be noted that total volumes in the month exceeded those of June 2015.
“Additionally, 2016 remains 9.4% ahead of 2015 over the first half of the year, which is significant against a 2015 figure, only 0.54% ahead of 2014 at the same point.”
