Dealers who have signed up for the ADESA Upstream remarketing platform can now bid on and buy stock at any time.
The vendors the used vehicles are sourced from include Arval, Motability Operations and Northgate Plc.
Jonathan Holland, managing director of ADESA in the UK, said: “Dealers don’t have a 9am to 5pm routine and are under increasing time pressure.
"So the ability to bid on, and buy, vehicles at a time to suit them is a real bonus.
"It gives dealers the advantage in being able to buy the best stock ahead of anyone else, also allowing them to be more agile in responding to customer demand.”
ADESA Upstream technology is built on a mobile app platform which allows dealers to take part in multiple daily online auctions.
Dealers can also view upcoming vehicles and set proxy bids.
