If the hood has 4 vents (two up front, two towards the rear), then it is a Trans Am hood and would mean that those taillights are likely not original to the car.
It would be cool if it really is a real S/E. I've only ever seen one of them in person that I can remember. Oddly enough, I just happened to drive passed that one again today.
*edit* here's an S/E (this one is an '86, notice the brake light) that was on Bring a Trailer.

Notice the "sort of a T/A hood" and also the Trans Am taillights that the '85 and '86 S/Es got.
