Suspension squeak, could be a hundred things, bushings, shocks, sway bar, who knows?!
I wouldn't worry too much about it.

As for the Ironman, my proton says the same thing, but if you really want to know if its a repaint, check door jams, inside enhine compartment, under rear carpet. If its black, than you have an original Ebony, if its white, then you have a repaint

The ironman also had monogrammed carpets, (and maybe the seats?)
