Q. Should we buy BS4 Venue or wait for BS6 cars. Buying BS4 now will retain car value and depreciation after April 2020?

Supreme court has given a clear judgement which makes sale and registeration of bs4 invalid. There is no separate provision given for resale of existing cars which means it equally applies to all existing cars. That means you cannot legally resale or re-register any existing bs4 cars after April 2020. would essentially become scrap if you don't want to use it. If you want to change your car in next four five years, better wait for bs6 and you will get resale value. Otherwise you will end up with scrap metal at the end of four years.

Bs4 is better because bs6 is come in more price

Undoubtedly petrol.
