@nithin there are multiple issues with BSE: 1. 20 depth data is not available, 2. Quantity of orders is usually very small in BSE which eventually result in lower sell prices.
Customer should have choice to keep default exchange as per their wish. Pls make necessary changes where customer can opt for exchange of their choice.
And for scooter I would also consider who’s giving me scooter early and giving me option to choose color of my choice 
So it does matter from which showroom I buy it!!
