I bought my G35x with 68K miles on it in May of 2011.
It is a fun car to drive and is extremely stable in rain and snow.
My wife drove it on her vacation and hit a lot of rain.
When she got back she did not want to give the car back to me.
I had to have a tie rod replaced ($165) and scheduled maintenance required that fluid for the transmission, transfer case, and both differentials be replaced along with a radiator flush which cost me $650.
Also the Bose CD changer died and I had to replace it with an aftermarket system ($400 which I installed myself).
The aftermarket Pioneer actually sounds better.
I will need to replace the Dunlop tires after 30K miles partially due to the AWD.
Performance and exceptional stability in rain and snow.
Improve seats, very uncomfortable seats, especially if your waist is over 34.
I had to buy a gel seat cushion for long trips.
Improve fuel mileage (only 21 MPG highway).
