Looking forward when she takes on her own policy, she’ll get lower quotes if Mum is a named driver.
Black boxes generally are good for cost and to develop safe driving. The insurance company will report / nudge on poor driving.
It’s better to be coached into safe ways than to find out when she writes off the car.
They used to say that there’s a 50% chance of a claim in the first year of driving.
And the best way of dying in a car collision is to be a car with a relatively new male driver being driven after 10pm. Worth saying, because cost is the least of anyone’s worries here.
Finally, when she does really need her own car, the cheapest solution might be a slower 1litre petrol car for a couple of years.
Happy birthday, Miss D
