I have been with Geico for 10 years, what kept me with them is that my daughter had just graduated high school and started college she asked to borrow the car because she was late for school, I said yes she got into a fender bender. Geico paid the claim and they even asked its my choice to add my daughter to my policy or not. Insurance only went up by $30 dollars a month.
For some, the best coverage is the cheapest car insurance policy that makes them able to legally drive on the road. For others, the best coverage is the type that covers the full cost of repairs on your vehicle when you file a claim. The only way to be certain you are fully protected is to purchase both comprehensive coverage and collision coverage. Each coverage has its own job to do.
