If you're looking for a fast, show-stopping and rare coupe, then there's very little that comes close to the Camaro. There aren't many around, mind. If you want one, you're going to have to spend some time trawling the classifieds and forums. You could also look at importing one from the United States, if you can't find a car in the United Kingdom that matches your requirements.
The Camaro's a well-known name in the American car scene. With only a handful imported by Chevrolet, it shouldn't prove difficult to sell. Owners will need to advertise the car in the right place, however, such as specialist performance and American magazines and websites.
