I'd really suggest you call your insurance company, and maybe a few others. There are so many factors that go into calculating your insurance premium, that what someone else is paying has little to do with what you'll pay.
I called a half-dozen companies, at least, and found that rates from one to the next varied as much as 50%. I went with the lowest quote, but when I renewed the first time, it went up 25%. I think I was the first kid on the block to get insurance for a Cooper S, and the insurers really had no clue how much to charge.
I had a 1998 Acura Integra GSR coupe (5-speed manual).
I was braced for a swift kick in the nu*s, but my insurance actually DROPPED when I bought my new 04 MCS!! I am paying around $775 a year for $500 deductable with Country Companies (large insurance company in the midwest). That comes out to less than $65 a month.
I'm 28 and married, have multi-car discount. While I don't have any claims in my history, I have more than my share of speeding tickets.
My insurance agent said my premium went down due to increased saftey ratings and lowered risk of theft. Whatever. Means I have more money for mods!
I'm paying ~1200 year. $250 deductable on collision, no deductable on comprehensive, multi-car discount, safe driver discount (some program state farm was trying out for younger drivers). I might call up ye old insurance agent and see if i might be able to get it down a bit. 26 y/o, male, maryland, no tickets or claims.
needless to say a brand new 05 Cooper S would cost more to insure than my 95 Geo Prizm.
Although last year I did get a rate drop with the whole you turn 25, you get cheaper insurance thing.
