First, I want to apologize for not getting a picture. It's difficult to do going the opposite direction on the interstate. But, there is a 2007 Screaming Yellow GT500 circulating around south Louisiana. The owner or Ford Rep participated in a high-speed challenge on I-49 between Shreveport and Lafayette. Maybe someone reading this participated too and got some pics of it. Screaming Yellow, no striping, race logo cling-on stickers and all GT500. I'd like to know what speed class it ran in.

 

Maybe it's the same one from this thread:

The car you saw was a pre-production model driven by a Ford engineer. The car is participating in the Car and Driver One Lap of America.

He told me it pretty accurately represented what the production model will be.

The model he is driving is not 500hp. He removed the cats to increase output. He also told me the ride height is representative of what we should see in a production model.
