Meanwhile, Pendragon is believed to have breached its banking covenants on its property joint-venture, leading to demands for a £20 million cash-injection, according to the Daily Telegraph.
Pendragon, together with joint venture partner Aaim, a property fund manager, have been asked to put millions into the venture that owns the vast bulk of the company's car showrooms. It is understood the joint venture has breached loan-to-value covenants on £330m of debt supplied by Royal Bank of Scotland.
Pendragon set up the sale and leaseback joint-venture in 2007.
