DETROIT, Jan 11 (Reuters) - General Motors Corp GM.N Chief Executive Rick Wagoner said the struggling automaker had enough funding to last through March but could still seek additional U.S. government loans beyond the $13.4 billion it has already been pledged.

Wagoner, speaking to reporters at the Detroit auto show, also said GM was still seeking a potential buyer for its Saab brand. "We're still looking," he said.

GM had warned that it was at risk of running out of cash before the Bush Administration cleared its request for emergency funding just before the end of the year.

In recent weeks, some reports have said GM executives believed the $13.4-billion in U.S. government loans would allow the automaker to survive even under its most dire forecasts for the U.S. market in 2009.

But Wagoner indicated GM could still opt to seek additional funding after a March review with U.S. officials intended to assess its progress in restructuring.

"The $13.4 billion is consistent with what we asked for through the first quarter under our downside market scenario, which is the way the market is running," Wagoner said.

"We will obviously review the whole plan and at that point we'll see what requirements are. But for now we think we're well covered through the period we asked to be provided," he said.
