I found these pictures over at the Trans Am Country web site. Before you get too excited, they're NOT official GM mock-ups, they're just someone's idea of what a new Trans Am might look like if GM were to decide to make one. Kevin Morgan from Trans Am Country made these, based on a picture of the upcoming 2007 Camaro.

This one is my personal favourite, but I'm partial to 2nd gen SE models

My fiancee says that if such a car were to be made, she'd definitely want a blue one like this
