The value of auto insurance for most of us with some kind of asset other than the car is in the liability coverage. A beater does not deserve a high coverage or low deductible for the collision or comprehensive, and it is easy enough to find an insurance company that will recognize that it has little to lose on that aspect of coverage. But most insurance companies price their liability product based on the assumption that, although you may be driving a $200.00 car, the guy you crash into may be driving a Rolls full of bank executives and their lawyers. If you have nothing else to lose, then the minimum liability required by the state may be enough, and probably will not be very expensive. If you own a house, or have any expectation of significant future earnings, you may not want to gamble on that minimum liability. For equal limits, there is probably not a lot to lose by going with a "cheap" insurance company, compared to a prestigious company based on some expectation of better service.
