Jardine Motors Group has signed up Manheim Auctions to remarket up to 50 surplus vehicles a week at its Leeds and Colchester auction houses.
The dealer group has also adopted Seller Advance, Manheim's valuation service which aids dealer cashflow.
Jardine Motors Group represents 24 franchises at more than 75 franchise locations.
Neil Hodson, dealer sales director at Manheim Remarketing, said: "The Jardine Motors Group is a well established and highly respected member of the franchised dealer community.
"Its appointment of Manheim Remarketing is a further endorsement of our ability to provide an all encompassing remarketing service while its adoption of Seller Advance sends a clear message that the benefits of our award winning valuation and automatic push to auction service is of real benefit to dealerships looking to manage and quickly release the cash tied up in their higher mileage and overage stock."
