I dont understand why you cannot afford the g35c? if you forego the sunroof and premium packages they offer, you still have basically what the 350 has plus your extra back seats you want. When i priced a g35c on the website, it was actually 1000 less than a fully decked out track edition and im talking about having comparable options on the Infiniti...

 

Here you go:

 

I did a quick video of me installing my new rear or back seats to my 2004 350z. It's a work in progress so relax. Vic out.

 

I had to cali-legal this bad boy, but I got to at least run it in all its glory before throttling it down.

 

Oooooh, aaaaahhhhh, wooow. (Sarcasm)
