Ford India — Dealer saying Insurance is at dealer must to deliver

Hi I'm vishnu from coimbatore. I booked Freestyle T+ diesel at suryabala ford coimbatore. Now he is saying I've to take insurance at dealer only to deliver the car. He's not delivering the car if I insure the vehicle at my choise. Please look in to the matter as insurance is my choise. I can insure it from any where. It's not compulsory to take insurance at dealer only. The manager is very arrogant and his behaviour towards the customers is unpleasant. People like this bring bad name to such a good company ford. A total of 45000rs he is chaging where as from other company with the same features I'm getting insurance for 30000 only
Please do the needful and help me to get my dream car.
