Mass has regulated insurance, meaning everyone’s rates are pretty much the same. It also means you must have insurance to put a vehicle on the road. There are not allot of options for insurance here because of the regulation and because we typically drive like Massholes, most companies don't want to insure us.
I personally use Commerce Insurance; they have been pretty good to me over the years. I pay $980 a year for the Busa, that’s with maximum everything and a $300 deductible. I believe you can get it down close to $500 with minimum insurance.
Hope that helps
