insurance is a total rip off... so no surprise there
the best advice is to shop around. call at least 4-5 places. make sure you understand the coverage they're giving for the prices they're quoting.
no one can say "my insurance place is the cheapest" because it depends on you. insurance cost is not only catered to the individual for such things as: driving record, previous claims, vehicle insured, age, color, sex, race, smoker, how often you masturbate. its also calculated by how many other similar individuals they already have. if they have a lot of <you's> , then the price will be higher at that particular company.
