I just got my April 2010 issue of Corvette Magazine and oh, snap! Guess what I saw? Gracing the cover is a 2009 GT1 Championship Edition Convertible. A car so rare, we’ll be talking about the record prices these special editions are sure to get at auctions sooner rather than later. Only 7 Black GT1 Convertibles were made and we are pretty sure that only one has been tuned by Callaway.
