beavis on that link above it says
"The slightly disappointing part is that the 35th Anniversary Z - also known as the GT4 in reference to the car's appearance on the Sony Playstation Gran Turismo game"
"While another 20bhp sounds like a lot, I'd be a liar if I told you that the GT4 (35th Anniversary is such a mouthful) feels gorblimey faster than a regular Zed. In fact, to start with you might even wonder if you've been mugged by a bit of marketing spin and that there really isn't a power increase at all. Give it a few miles, though, and you'll detect the engine's slightly greater eagerness to please, coupled to a sense of improved fitness. You begin to use the revs more than you do in the standard car, and can feel that at the upper end of the mid-range there's more energy available. What you still won't feel too much like doing, however, is revving the rumbly V6 all the way up to that higher redline, as there's no discernible advantage in doing so."
so does that mean the GT4 is the same car as the 35th annivesary?
