WARREN, Mich. >> General Motors Co. says it’s been restoring some prized Chevrolet Corvettes extracted from a sinkhole at a Kentucky museum.

GM has received two classic vehicles that were among eight gobbled up by a 40-foot-wide by 60-foot deep hole in February at the National Corvette Museum in Bowling Green. Among them is the 1 millionth Corvette, a 1992 model, which had significant damage.

The Detroit-based automaker invited the media Wednesday to see the vehicle before restoration begins next month at its Design Center Fabrication Operations in suburban Warren. The work is expected to take six months.

A 2009 ZR 1 was restored and returned to the museum. A 1962 model is expected to be worked on at a specialty shop.

The museum is near the factory where Corvettes are made.
