You are (not) paying State Farm for your 25 year old car, since they would not insure it for collision or comprehensive, in other words to fix or pay for any damages to your car if in an accident.
What you are buying is liability insurance, which pays for the (other) car or driver if in an accident for their car damages and (any) injuries to the driver and/or passengers. Now if you hit a new car, then they could pay on average of $5,000 to $10,000, just to fix. Or with injuries, that is where the money is, thus add thousands to that. Liability insurance is protect you from being sued.
Liability is based on (risk), in other words, your age, zip code, any (prior) accidents or tickets w/in the last 3 to 5 years. Now many insurance companies will charge you less for low mileage, just like they charge you more if you drive more miles per week, like 20 miles to work or 40 miles per day.
So, have you compared other insurance companies to see if you can get your cost lower or not? My guess is (not) or maybe $50 or less than State Farm.
