With an initial size of six acres, the centre has the capacity to extend to 10 acres to meet the projected needs of the business.
Based at Gross-Gerrau near Frankfurt, the company said that within an hour's drive of the facility there are more than 6,190 franchised dealers and more than 4,000 independents.
Importers and leasing companies based within a 30-mile radius of the site include Opel, Skoda, Hyundai, Saab, BMW, Renault, Avis Fleet Services and Masterlease.
It is also a 20-minute drive from the busy Frankfurt airport and boasts a number of conference and training rooms.
Centre managing director Peter Dietrich said: 'We aim for this centre to become a meeting point for the motor industry.'
The centre hosts both open and closed sales. A closed sale could include a manufacturer restricting buyers to those from its own dealer network, although neither are open to members of the public. It is purely a business-to-business centre.
Payment is by cheque only so there is no need for any cash to be kept within the centre and dealers attending sales have to be pre-registered.
Dietrich said: 'We negotiate with vendors the minimum price for a car and those negotiations can be tough. We want to provide the right amount of cars at the right prices.
'This centre is not just a physical auction – we offer full remarketing solutions including Smart repairs.'
