Holy shit...looks exactly like the one I almost died in about 4 yeas ago!
I'd be interested to know if it is a rebuild...if it is then it's the one! My buddy was looking at one just like this(or this one perhaps). We went for a test drive, me in the passenger, my buddy in the back, owner was driving. He was showing off and shit...ended up t-boning a chick at an intersection in poco...we were going around 130-140km/h.
He just punched it when the light went green...we were like wtf!
The one we were in was a '97 GS-T and had a Greddy 18row and I think an Apexi N1 exhaust....but it had the, ummm "shopping cart" style GT wing.
