The service, called Vehicle Remarketing Solutions (VRS), will go live at the start of next year and aims to provide inspection, refurbishment and remarketing services for fleet customers.
But dealers can register the car they want with VRS, which will contact them when a car that meets their needs becomes available.
The service promises to offer motor retailers quick and efficient access to a wide range of vehicles, mainly under two years old. Manheim will offer dealers a quality guarantee on every vehicle they buy through the service.
Pilkington will report to John Bailey, chief executive of Manheim Auctions, and will be responsible for setting up the new business. Initially, VRS will set up a Midlands headquarters to concentrate on the UK market before expanding on to the continent through Manheim Europe.
Phil Deegan is to replace Pilkington at GRS. He joined the company earlier this year as operations director after 11 years with GE Capital, where his roles included responsibility for vehicle remarketing and business development.
Pilkington was previously deputy managing director of Manheim Auctions before joining GRS.
