Is it legal to purchase two different insurance coverages for a single car? In my case my agent forgot to cover bumper to bumper in the policy, so can I enhance or buy another car insurance policy?
Ans: It not illegal but it not advisable to have two different insurance coverages for a single car.
However, in your case you can raise a request to your insurance company to add the said add-on.
If insurer is unable to do so, you can purchase an alternate fresh policy with the zero-depreciation add-on (bumper to bumper) & get the first policy cancelled.
