The last car buried is a 2001 Mallett Hammer Z06 Corvette. The vehicle is upside down, about 40 feet beneath the surface.
National Corvette Museum spokeswoman Katie Frassinelli says the workers hope to recover the car Wednesday or Thursday.
The prized cars were swallowed by the sinkhole that opened up in February beneath part of the domed section of the museum in Bowling Green.
Frassinelli says the damage has been progressively worse as each car was pulled out in recent weeks.
The eight cars will be on display at the museum through August. They will be shipped to a General Motors plant in Michigan to be repaired.
