I really don't see how you can say they are "near identical"
The side skirts might qualify for that, but thats it.
The front end, nothing at all. Saleen's is very vented and the lines are very disimilar from the stalker kit
From a side view, the stalker has scoop shapes in similiar locations that the Saleen has its vents/scoops but they are not similar at all in the front, and still different in the rear
as for the rear view, the biggest similarity is the "wraparounds" around the exhaust tips. The rectangles and vents are too different to be compared. The Text in the bumper? what mustang DOESN'T have that? And the spoilers... there is nothing there thats even close to similar
Overall you could say there are a few shared elements that carry similar themes, but the cars and parts (save for the aforementioned skirts) are nowhere NEAR identical
I don't give the Saleen more merit because of the name, but because it is better executed and looks alot nicer than the Stalker kit. That being said I would NEVER install a Saleen body kit on a New edge.
