Mercedes just announced that it will showcase the AMG GT3 at the upcoming Geneva Motor Show early next month, but there’s a good chance that anyone likely to buy one already knew that. In any event, the company also confirmed this morning that the new GT3 will be available to customers in the U.S. and elsewhere, but that sales as was the case with the SLS GT3 will take place through AMG Customer Sports in Affalterbach, Germany. Mercedes-AMG will release more information about its gentleman racer model at the Geneva Motor Show.
