Q. If I buy a BS4 Car today, can it be resale after April 1, 2020. Will new registrations of used BS4 vehicles be done after April 1, 2020 - City?

Important point is this that no BS4 engine vehicle where renewal is due after March 31st, 2020 will get it. So the second hand car market of BS4 engine are going to crash like anything. Media is not highlighting this fact because car companies are still clearing their BS4 stock. Usually we Indians exact one car life is between 18-25 years with minimum 1 or 2 renewals but now with BS4 engines, it's not going to happen.

Yes. But you will get Lesser Resale Value. Whenever buying Electric or Electronic. Mechanical Things , Gadgets etc. Always Try to Buy New & Latest Technology Models. It may be LITTEL Costly but you get Value for Money .
