im not sure of what you mean by "tempered", i think what u meant was tampered? It is normally extremely difficult to find out if the odometer has been altered. If the car shows a lot of wear and tear on the steering wheel, the seats and other parts of the car with a very low mileage reading, the odometer may have been tampered with. This is definitely not a fool proof way of finding out if the odometer has been tampered with. My recommendation would be to put the car into place like C*R CH*E*KS or the agent of the car, e.g.: if it is a toyota, T*YOTA L*N*A. It will cost around 7000 rupees or so and it may be cheaper or more depending on the agent. They will inspect the car for any damages, accident repairs and other things you should know about the car and provide you with a report,
I hope i was of some help to you
Cheers
