US carmaker Chrysler has opened its books to buyout specialists Cerberus Capital Management for an in-depth look at its finances, a newspaper reports.
According to the Detroit News, Cerberus is the first potential bidder to visit Chrysler's headquarters for talks.
DaimlerChrysler chief Dieter Zetsche said in February that all options were open for the motor group's US arm.
Four private equity groups, as well as General Motors, are rumoured to be interested in buying Chrysler.
The newspaper also reports that the private equity firm Blackstone Group is meeting with Chrysler management later in the week.
The US arm of the German carmaker is in the process of cutting 13,000 jobs as part of its attempts to return to profitability by 2008, following last year's $1.48bn (£769m) loss.
Mr Zetsche said in Geneva on Monday that he is also not ruling out a sale of its finance arm, Chrysler Financial.
