These sites often attract your interest with competitive rates, but then transfer you to a different site to continue shopping and complete your transaction, often at a far less attractive rate. This is because lead generations sites are paid to sell your information to an agency or insurance company, not to present you with the rates on car insurance.
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.

Results: After working my way through the DMV.org quoting process, I discovered that they don’t actually provide car insurance quotes. Instead, they just provide you with links to other websites where you can get a quote. In my case, it gave me exactly two links: to Esurance and Allstate. Clicking a link to go to one of these websites required me to start all over with the quoting process, leaving me wondering why I’d bothered with DMV.org in the first place.
Car insurance will prove a benefit if you ever experience a wreck, vehicle theft or other unpreventable problem on the road. The policy can help pay for such concerns as your own vehicle damage, injuries and related costs. Coverage can also pay for the damage you cause others if you are deemed at-fault in a wreck. With your policy, you can reduce your chances of significant financial losses after an unfortunate accident.
Type of car: If you have an expensive or powerful car then you are seen as a higher risk for a number of reasons. If it’s expensive, it has a higher risk of being stolen. If it’s powerful, it’s deemed more at risk of getting into an accident driving at speed. If you want to see how your car impacts your insurance, you can check which insurance group it’s in for an indication.
