The car is amazing. While the interior is lacking in some specifics (back seats aren't faux suede like the front seats, interior lighting is almost non-existent, storage lacking for front seats) the exterior aesthetics are awesome.
LED DRLs, though they turn off when the headlamps are turned on, skirting to make it look lower, 18" alloy rims specific to the Nismo and a reimagined spoiler. The drive is amazing in a 6 speed MT and the car handles wonderfully on mountain roads.
The only real downside is that Nissan cosmetic parts are backordered for upwards of 5 months on these puppies, and Nissan doesn't seem to assist their customers when it's brought to their attention.
Nismo badging on the interior and exterior, suede and leather-wrapped steering wheel, leather wrapped shifter knob, navigation package with iPod ready connections, controls on the steering wheel, handling on mountain roads
More storage space in the front (console), better interior lighting like a dome light in the back. Nissan needs to keep cosmetic parts on hand for fender benders - they happen all the time in large cities.
5 months for a bumper on backorder is just outright ridiculous.
