The varied rate of IDV's reflects different rates of premiums. Insured Declared Value, abbreviated as IDV, is the current value of the car after being adjusted for appropriate reduction. The rate of depreciation depends on the age of your car. Older the car, higher would be the depreciation and lowered would be your IDV. And it affects the Sum Assured. Hence, compare the IDV quoted offered by different car insurance plans is a must.
You are required to submit a renewal notice from your previous insurer. If this doesn’t state your (NCB) entitlement or if it is not given to you by the company then call your insurer and request confirmation of your (NCB). Alternatively, you can submit your previous insurance papers and declaration that you are entitled to receive (NCB). However, if you are not eligible for NCB and wrongly claimed for it then the insurance contract is void ab initio and the insurance company reserves all rights to reject your claim.
Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
This is pretty ridiculous considering the fact that: 1st, I had regularly asked my former insurance company for reviews and discounts; 2nd, I recently got a speeding ticket in a school zone (which I am a bit ashamed to say) just before I switched; and 3rd, that $1,100 savings was before I got an additional discount for bundling my home insurance on my policy (which is a lot lower now too).
