You can transfer NCB of old car to new car
PLEASE CORRECT ME.
NCB IS POSSIBLE IN THOSE CASES ALSO IF YOU SWITCH OVER TO THE OTHER INDURANCE COMPANY.
BY THE WAY, WHAT INSURANCE COMAPNY YOU DEAL WITH? more
When you buy a new car, under a 'comprehensive' policy, you pay for Own damage (OD) as well as third party liability(TP). OD Premium is calculated on the original value of car and there is zero 'no claim bonus'(NCB). After one year, if there is no claim, you get a NCB. This is in the form of discount on your OD premium (calculated on depreciated value of car), which progressively increases with every claim free year, going up to a max of 50% (it was up to 65% earlier, now 50% ).
When you buy a new car, you can now ask for zero dep (depreciation) policy- this option is now available for the last few years. In this option in case of claim the insurance company will pay you value of replacement part without depreciating its value (which they do in a normal policy).
Hope this answers your query more
