State Farm car insurance, like all other insurance, is a different price for each person. Nearly any number could be the price for someone. $50, $100, and $10,000 are all equally correct answers, because any of those numbers is going to be the price somewhere, for someone.
The main factor in insurance prices is where you live. In some places, insurance from the most expensive company will cost less than half of what is costs from the cheapest company in other places. Also, in most places, the price is different for men and women, especially for unmarried drivers under 25.
