First, make sure you're not spending too much money insuring a pile of junk. Of course you have to keep some insurance, but going keeping full coverage on a clunker means you may be insuring it for more than it's worth -- and in case the car is totaled, you'll be paid out based on the car's actual value rather than the value at which you insured it. (Check Kelley Blue Book for your car's current value.)

Of the insurance options, collision and comprehensive coverage should be the first to go when a car has depreciated significantly. However, resale values vary, so you need a baseline to determine when you've reached that point. If your car is no longer worth at least 10 times the cost of the premium, ditch these options.

Low-mileage drivers -- people who commute using public transportation during the week and only drive at night or on the weekends, for example -- can qualify for a low-mileage discount. Other discounts include those for drivers with excellent safety records, long-term policy holders, and drivers whose cars have specific safety features.
