It really depends on your age and insurance company along with driving history (tickets).

My insurance ranged from $600-$690 every six months. I was 25 when I bought my R, I've been insured by Nationwide since I was 16, I've had five speeding tickets (but went to traffic school for all of them), and now I get a multi-car discount because I own two vehices. My insurance was more on my WRX.

I'm about to get another ITR, so I expect my insurance to be less this time around because I'm older and the car is also older.
