Hi there just thought i'd add what i know about the 2006 350z.
The interior will be made with softer materials, re-positioned heated seat controls, revised look centre console with factory sat-nav option(same nav as pathfinder), cup-holders in the doors, speed sensitive power steering, bluetooth was mentioned for the stereo system, revised front headlamps to include LED side lights and bi-zenon main, slight alterations to front bumper area, LED rear stop lights, revised camshaft profiles and variable exhaust timing to help 300bhp but slightly less torque spread over larger rev band. Apparently standard kit for GT will include Rays. If i can find the paperwork from the dealer i'll update any other bits i've missed so even though i've placed a deposit i'm not sure entirely the price or options
Still whatever it is hopefully it'll be here soon
