Yeah I questioned that earlier too...because on carpoint it's listed as a 4 seat coupe clicky .....I'm guessing its just an accidental thing. Strangely there are no pictures of the left side of the car. At all. Edit: Messaged the guy..its a 2 seater.
As for there being no boost guage built into the speedo, as another member mentioned, all late model twin turbo z's were made without them. Dont know why, possibly because the boost guage is prone to stuffing up? So was just easier to leave it out?
