James,
Firstly welcome to the board, glad to have you 'on board'.
I'm no expert and I'm sure others will correct me if I'm wrong, but it is a GT5S model, which appears to have had some modification to the front fender flares through addition of an air scoop to the front and air oulet to the rear side of the front fender.
Definitely a great looking Pantera and it wears that 'metallic orange rust' color well.
