The Williams Group has secured a £20m new banking facility with Barclays Corporate.
The dealer group has 10 dealerships with BMW/Mini, Land Rover and motorcycle franchises employing some 600 people across Bolton, Liverpool, Manchester, Rochdale and Stockport.
Last August it expanded with the acquisition of David Holmes BMW in Stockport.
Managing director Nick Cook said: “Barclays Corporate has been very supportive of our requirements and will play an integral part in our plans for future growth.
“With the new financial structure in place, we intend to be pro-active in taking advantage of the opportunities the current climate presents.”
