The robot looks even more robotic, I like it.not sure if ive posted this before but that refeshed front end was been testing since October of 2014 with the new V motion grill they are shoe horning into the GTR
a japanese mag did a render in December of 2014 based on the spyhots and possibly real info and over a year later it looks dead on ( not not 100% if the vertical DRLs like the Z are confirmed)
