Average cost of car insurance?

$150.00. Does this help you? There are far too many factors that go into computing an insurance rate to answer on a forum like this. To properly compute an insurance rate you need: Year, make, model, serial number, dob of insured, all drivers information, all household residents information, drivers license numbers, social security numbers, driving records, accidents or claims records, prior insurance carriers, garaging address, vehicle usage, etc. There are far too many factors that go into figuring insurance so a question like this can't be answered here.
