The Chevrolet Corvette, one of top icons of America autos, has hit another milestone--1.5 million units built.

Corvette No. 1.5 million--a white convertible with red interior, the same as Corvette No. 1 in 1953--rolled off the assembly line in Bowling Green, Ky., on May 28.

It took 24 years to reach Corvette No. 500,000 in 1977, then 15 years until Vette No. 1 million was built in 1992, and then 17 years to this milestone. All the milestone cars are white with red interiors.

After a bit of time in the Chevrolet promotion fleet, Corvette No. 1.5 million will be kept at the National Corvette Museum in Bowling Green. The museum also has Vettes No. 500,000 and No. 1 million.

Chevrolet also used the milestone to set the sticker price for the 2010 Corvette Grand Sport models. The Grand Sport coupe is priced at $55,720 and the convertible is priced at $59,530, including shipping charges. Grand Sports include chassis upgrades to boost performance.
