In Europe for the C6 they were not sold as Chevrolet, since they used that make for rebadging Daewoo cars.
You could not find the Corvette on the Chevrolet websites of EU states, and there is a separate site for these: http://www.corvette-europe.com/
But now that seems to change, for 2011 they reintegrate it in the Chevrolet model line...
