This isn't a trick question, is it?
Actually, GM wants to sell as many '03 Corvettes as they can build...after all, it IS a business. You might want to visit your friendly dealer in early May to order what you want, and you may have to wait a while to get it, but...nah...it will be no more difficult than getting any other current model 'Vette.
You aren't going to tell me now that they cancelled Electron Blue for 2003, are you? :s
