A durability prototype used to develop the 2013 Shelby GT500 will go under the hammer at Barrett-Jackson event next week.

This prototype dates back to 2007 and was used to test all the systems for the 2013 car in terms of performance and durability. Its hard and miserable life included a 24-hour test at Sebring, during which it achieved top speeds of up to 150 mph.

Carroll Shelby himself drove this prototype, when he was not harassing his employees, and he is extremely proud of it, because it resulted in a car that he says is what he always wanted to make.

Not sure what exactly you can do with a knackered prototype. You can probably tell your friends you have a piece of Ford’s history, or you can drive around in it and pretend you are an engineer or test driver. But they will be doing good things with the money you pay for the car, as all of it will be donated to the Juvenile Diabetes Research Foundation.
