The SnappCar Keyless system tracks the mileage of your car. For some models, it is not possible to do this with the dashboard data, so we track it using GPS. The GPS tracking can have a 5% deviation, so we recommend you do check the mileage regularly. If the difference becomes too big, please let us know the current mileage by contacting us here so we can update it for you.
