(Adds more wagoner comment, debt insurance cost increase)

PITTSBURGH, June 26 (Reuters) - General Motors Corp (GM.N: Quote, Profile, Research) has adequate liquidity to carry it through the end of this year and has many options beyond that, Chief Executive Rick Wagoner said on Thursday.

Wagoner sought to reassure investors and analysts with GM shares falling to their lowest level since the mid-1950s and new concern surfacing on Wall Street that the auto giant may have to raise capital.

"As we've said before, we've got a very good, solid funding base under any scenario we see, solid through the end of this year," Wagoner told reporters after attending an economic summit with U.S. Democratic presidential candidate Barack Obama.

"We have a lot of options to fund beyond that," Wagoner said.

GM, Ford Motor Co (F.N: Quote, Profile, Research) and Chrysler LLC are fighting a severe pull-back in sales of bread-and-butter sport utilities and pickups amid $4 gasoline as they scramble to restructure operations.

Earlier Thursday, the cost to insure the debt of GM and Ford hit record highs over liquidity concerns.

Wagoner said GM has moved "quite proactively" to address the dramatic consumer shift away from light trucks and has taken "some very tough measures."
