2010 3.5SR  update
 Great Car when Brand New! Currently have 11500 miles and now I have plenty of rattles along with road noise. Engine performs well without any problems, but it struggles to meet my performance(speed) expectations. Had previous VQ35DE engines and loved them all, but this one is not performing as I hoped. Hit the gas from a stop car takes off, give it gas @ 60 mph the car creeps to 80 mph. I noticed that this VQ does not require 93 octane maybe thats the problem. Car works fine and all of the gadgets seem to work as designed i.e. Navi, Bluetooth, HID lights, AC.  I strongly suggest nissan improve the paint because it scratches and chips easily. No way did these cars go through 5000 test as advertised.
