Saab's bankruptcy administrators say they are evaluating bids for the Swedish brand and aim to make a decision in the next two months.
The administrators did not disclose the bidders after a final deadline passed this week.
Chinese carmaker Youngman is the only company to publicly register its interest in buying the company. Media reports have said that India carmaker Mahindra & Mahindra has made an offer and so has a Japanese-Chinese consortium that wants to produce electric vehicles at Saab.
Bankruptcy administrator Hans Bergqvist told the Swedish press that all the bidders want to restart car production at Saab's plant in Trollhatten, Sweden. He said the bids were being evaluated as a base for continued discussions.
Bergqvist said Saab has debts of 13 billion kronor ($1.9 billion) and assets of just 3.6 billion kronor. He said he hoped the successful bidder would pay more than the assets were worth.
