this one went through on ebay just a couple of days ago. Very good value and no one ended up bidding on it. May be worth getting in touch with the seller.

As regards spec. It seems to be down to what you are going to do with the car. If you were going to do a lot of mods like change the wheels or a re trim or new stereo, it's not worth going for a GT. If you like it in mainly factory spec then it's worth considering. I like the rays and yes they are lighter. The GT4 wheels are heavier. All new Z's are now the same spec engine as GT4's. Don't think there is that much in it but you get more exclusivity with a GT4 over the rest of the Zs as they are a limited run.
