After crews fetched out the last of the classic Corvettes devoured by a sinkhole in Bowling Green, Ky., General Motors officials and the National Corvette Museum's board of directors now face the dilemma of which vehicle gets restored and which don't.

No one was injured when the sinkhole left a 40-foot-wide, 60-foot-deep hole in the middle of the museum's Skydome on Feb. 12, taking eight priceless Corvettes down in the process.

CNN reported that the estimated total cost of the Corvettes amounted to more than $1 million.

Board members will meet with GM as well independent restorers next month to discuss a new plan regarding the restoration, said Dana Forrester, the board of directors' lead Corvette restoration member.

"We'll listen to what they say about it, and then we'll make a decision as to which car gets restored and to what degree," Forrester said.

When the last car was pulled out of the wreckage on April 9, members of the board and National Corvette Restorers Society assessed that the damage was greater than they originally expected.

"The last three or four cars that came out of the sinkhole ... we didn't expect them to come out looking quite that bad," Forrester said.

Forrester added that "recent discussions have changed what the original thoughts were," and it "may not be possible" to restore some of the vehicles but to let independent restorers handle it instead of GM, despite the company promising back in February that it would "oversee" restoration.

The National Corvette Museum is a privately funded by donors and is a not-for-profit facility ran by its board of directors. It has 28,000 members, CNN reported.

According to GM, Corvettes are the most collected vehicle in the U.S. and the "world's longest-running, continuously produced passenger car." It was introduced in 1953 and since then, 1.5 million have been developed.
