Is the 2004 used Infiniti G35 coupe a good car for a 17 year old?

It you are rich, then yes.
It is an expensive car.
The Infiniti G35 Coupe is a Nissan 350z under the skin.
It has a 287-292HP V6 engine.-raises insurance
It is RWD.-raises insurance
It is 2 doors-raises insurance
Luxury car-raises insurance

You should start off with a slow cheap car so the insurance will be cheap.
Maintanance and repair costs would be cheap too. If you drive at least 2 years without getting into an accident or getting a ticket, then go for the G35. The insurance will not be as high.

The Infiniti G35 Coupe/Nissan 350z is on the top ten list of most expensive cars to maintain.

Its very popular... I wouldnt see why not. Insurance might be a little pricy.

it depends on your style and what u like
if your a guy that likes 2 door small type of cars the the g35 coupe is for u (not to get me wrong i love the g35)
but if ur a guy that has a big personality and likes to be bright and bold then go with something like a 300, or catty
