...how much does it cost to insure an Impreza in the US?

I'm not quite sure how car insurance works in the UK but in the US insurance rates are different from state to state. I am 25 and live in Massachusetts which has some of the highest car insurance in the country (top 5 at least) and with a new WRX my insurance (with a $500 deductible, should I get into an accident) would run me less than $700 a year. Right now I own a '95 Toyota 4Runner and my insurance is about $800/year. Massachusetts insurance is regulated so there is less competition between companies, but in some other states one can get very discounted insurance rates. (not that $700 is bad )
