Driver's seat: you can see the unique driver's seat round stitch near the front (steering wheel edge) of the seat. But as stated before, the ENTIRE seat is leather!
Passenger seat: I tried to capture the stitching/seam pattern around the side side and back of the seat to show you how it matches all the other seat patterns in the 370z.
Third pic: just to show the power seat controls, and the heated seat switches.
So, if this guy replaced the stock seats with these, where could he have gotten them? It really doesn't make any sense. Even if he got them from Nissan, who knew Nissan made them this way? If they're aftermarket, then someone is really copying Nissan's design; and then he spent a lot of time to find seats that would fit in with the OEM seat brackets to accommodate the power seat switches.
I don't understand!
