The cost of a comprehensive cover is several times that of a stand-alone third-party cover, since damage claims are more frequent than third-party claims. Until now, the premium for motor third-party insurance was calculated on the basis of a schedule of rates provided by the Tariff Advisory Committee, an arm of IRDA, the insurance regulator. But IRDA has done away with the motor tariff. The compensation to the victim is largely decided by the earning capacity of the accident victim.
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.
