Imo, I would not go for the auto, unless it suits your driving or needs, one thing that has been reported on here is, if your planning to mod (stick an aftermarket exhaust on), the auto does not give it its full potential, and some people have said does not sound tha grear. I would go for the manual bud, cant beat it, and the Z is an awesome car to chuck it up and down the gears
the one on here, that you have spotted, i dont no what or who's it is, but at least you will know it will have been looked after, and if a respected member, you should have no worries at all bud
