hyundai cars - Olx car fraud

I was browsing through the old ads. Suddenly saw an add of Hyundai i** **** model with just **k kms run @******/- Rs. Thought there should be some EMI's which would not be mentioned so contacted the ad poster and enquired if it was genuine. He told he was from Army working in mysore airport.
I told him I liked the vehicle and the price of the vehicle. I asked him if the vehicle is in Bangalore or mysore. He told it is in Mysore. I asked him to show me the car in person as I was ready to travel to Mysore airport. He told his posting is changed to some other state due to which he had to sell the vehicle at such low cost and he cannot come out of airport to show the vehicle.
I sensed something suspicious. I asked him to share his army id. Initially he denied, anyhow I convinced him to share the card. He shared the information and told me that he will check the courier charges from army transport. I started looking for his profile on Facebook and Instagram. I didn't get any information.
I verified the RC details online and found that the car belongs to a resident in Bangalore.
I told the person to deliver car somewhere in mysore itself. In the mean time I started researching online about the same and got to know about all of these scams.
I became more curious about it and verified if the army id shared with me was fake or genuine.
Finally found that the Id card was tampered with wrong information on it.
Called up the guy and threatened him about his evil deeds and told him that I have raised a complaint on him. Immediately the guys sends few more images of the Army post Office.
I again started researching on those images. I finally found one of those images were from Google images.
Again threatened him about his deeds. He suddenly removed the add from the olx.
I started searching again on olx. Immediately he reposted the same image with different mobile number as a different add with the higher price.
Guys, please don't fall prey to these kinds of scammers. These are there tactics to cheat people and do scams.
