I bought my 2008 G35 S, Black on Black, Nav, Premium for 31K new at Riverside Infiniti. 28k for a G35 with 15k miles on it seems high. I just could not beat the deal on mine, especially compared to what else I was considering (BMW 335i, 48k).

 

I don't think anyone can beat Mike's prices from Riverside.

looks like you got a great deal on yours.

On a side note. The G's engine doesn't fully break in until after 10k miles. So the OP will enjoy the G fuller sooner.

 

Trust me you can enjoy the G before it is broken in, you dont have to jam the accelerator to enjoy it. (especially when someone like me comes from a honda)
