Manheim UK has broken its monthly auction sales record for the third time in 2015.

The company said its figures from July this year show that it sold more units across all of its sales channels than any previous month.

Manheim's auction sales volume was up 6.4% year-on-year from July 2014 and was 13.1% higher than the total units sold in July 2013.

Average unit selling price has also seen growth, with data from July 2015 showing a 2.7% increase from the same month in the previous year.

A record of 38% was sold through its online platforms, including its remote bidding system, Simulcast, in July.

Michael Buxton, chief executive officer at Manheim UK, said: “To break our monthly sales record for the third time in 2015 clearly shows that we are not only growing our business, but that we are growing it sustainably by developing our customer relationships and consistently delivering impressive performance.”

In May the company launched its new website, which Manheim said is already receiving more visitors than its predecessor, and is also showing growth in visits from customers accessing it from mobile devices.

Manheim also said that the average number of days cars are kept in stock were nearly 2% down year-on-year, and vehicle grade had also improved.

The remarketing firm explained that it has previously engaged with vendors in demonstrating the positive return on investment that can be generated from reconditioning lower grade vehicles.
