Check out the link. I bought an EX first and traded it in for 09 FX35 with Nav and Premium packages.

The technology in the car is well done. Everything works together. The Nav system would be better if they took off the safe guards for data entry while driving. iPod control is very user friendly. Bluetooth connects and works easily with both my BB Storm and wife's Instinct.
Interior layout flows well. Seats look great and are comfortable. Rear seats can fit 3 adults without a problem.
My one dislike is the 7spd tranny. It's great for highway cruising but in traffic (speeds under 40mph) the tranny is always hunting for the correct gear. It jerks into gear somethings. Driving in DS mode with the paddles shifters is a lot of fun! I still own the 06 G35 coupe and the gearing in that 5spd is far better than the new FX.
Let me know if you have any detailed questions.

I always wanted to have a J30t as a daily driver
