Almost all car meters can be tampered, digital & analog both have different methods to do so. Apart from checking service records, tyre & battery manufacture dates, dates on glasses & cross checking these with the odometer reading, there is no other way (easy/ cost friendly way) to check if meters are tampered. In case of digital Odometers when someone tries to reset the meter, the device does not get damaged.
The cost of resetting a swift odometer (for example) is about 1200/- max in Bangalore, the odometer cost for a swift VDI is about 75xx/- rupees.
