If you live in an area prone to car theft and vandalism, you'll probably sleep easier with comprehensive coverage at your side. Though car theft numbers have steadily decreased over the last several years in the U.S. — actually dipping below 700,000 reported cases in 2013 for the first time since 1967, and remaining at those levels the years following — the odds are still less than encouraging.
If you have paid off your car, comprehensive coverage is optional. It may be a good idea to find out the Kelley Blue Book value of your vehicle. Would you be able to pay that amount to repair or replace your vehicle if it were stolen or damaged in an accident? If you can't afford to pay much out of pocket, then buying optional coverages, like comprehensive coverage and collision coverage, may be a smart investment.
