Okay. Lets clear up what EXACTLY the 350 Z is and the G35 is.
The 350 Z (also known as the fairlady Z) is the latest car in the 3xxZ line started years ago by Dautsun.
Now here's where it gets important because calling the G35 an expensive 350Z is an outrage.
The Infiniti G35 Sport Coupe is the US Domestic spec Nissan Skyline R35. If you're fortunate enugh, you'll see a G35 labeled as a nissan skyline 3.5GT. The people that bought these paid a heavy premium to get one of these cars.
