I'm in the same boat as half the people that have posted here. I don't like the wingless look - makes the car look skiddish, like it's lacking something.
I'm into the whole clean looking thing - no obvious mods. As such, people look at the car as know it's not stock but really couldn't tell you whats changed (of course Supra owners would be able to write a list out though).
If it suits your desire, I say keep it. If it were my car, I would lower the back and put the wing back on her. Great car!
