Last year at the Barrett-Jackson Scottsdale auction Ford has managed to sell a Grabber Blue Boss 302 Laguna Seca for an impressive $450,000. At this year's event the company will once again come with a special 2013 Shelby GT500 and they hope to raise the same amount of money. All the proceeds will go to the JDRF.

Its true Ford did not revealed any details just yet on this "special" Shelby GT500, but as no unit has been sold just yet we expect this to be the first production 2013 Shelby GT500. We will have the official confirmation in the upcoming weeks.

However, under the hood you will see the same 5.8 liters V8 engine that delivers an impressive 600 HP.

The auction will be held at approximately 8:30 PM January 21, 2012, so if you are interested you have to mark this date. But until then we expect the GT500 Convertible at the upcoming Detroit Auto Show.
