Is it mandatory to buy BMW X3 from the nearest dealer or one can buy it from any dealer pan India?

You can purchase a vehicle from any city in cash only but in order to drive it on your city you have to register it from RTO from your city which requires a cost. If you want to buy in finance than you need to have a valid proof of that city only. Moreover, we would suggest you walk into the nearest dealership as they will be the better person to assist you.
