Non-payments

Dear Sir, My all family stay abroad. 3 months ago I had an agreement with my friend to sell our car for 7 lakhs (INR). It was on urgent basis as we were completely moving abroad. He handover 3 cheques of RS 250000/-, RS 300000/- & RS 150000/- which he said can be used after 15 days. I handovered the car and all related documents along with transfer papers. As per his instructions when I deposited the cheque of RS 250000/- it was bounced. When informed he said there might be some problem with the system. 2 Months passed and I didn't received a single penny. After many arguments he made a transfer of RS 250000/- online and said the rest will be transferred in a week. Its been 3 months and we do not have any contact to approach him. He is not picking up call or responding to any of my msgs. It is a clear indication that he is not going to pay any amount further or return the car. The only proof I have is remaining 2 cheques of RS 300000/- & RS 150000/-. Please advise what to do in this situation. What legal action can I take against him and what are my chances of getting back my money or car. I would be very thankful to you for your advice. Thank you.
