I have auto insurance through Liberty Mutual and they are the cheapest auto insurance for me.
Other cheapest auto insurance companies are American Family Insurance, Geico Insurance, State Farm Insurance, Nationwide Insurance, Progressive Auto Insurance.
If you have homeowners insurance already or renters insurance then your current insurance company can usually get you a cheap deal on auto insurance when you bundle.
However your driving record, age, age of your vehicle and the state you live in also factors into the cost of your auto insurance as well.
Among national auto insurers, USAA Insurance has the cheapest auto insurance rates, at $36.00 per month, with State Farm in second place, at $44.00 per month.
The cheapest local Auto insurers are Auto-Owners, at $40.00 per month, and Farm Bureau, at $39.00 per month.
