Zero-depreciation policies have become the top choice for 95% of new car buyers, according to a study by Policybazaar. These policies, also known as bumper to bumper coverage, do not deduct for part depreciation as vehicles age. This has led to increased claim frequency as claimants are no longer left with out-of-pocket expenses despite the intention to cover the replacement value of old parts. The average claim amount under zero-depreciation policies is higher than those without, indicating that car owners are now more conscious of the external appearance of their vehicles.
