We once ran a thread about travel insurance and I for one found it very useful.
We may not like to quote actual figures but the names of insurers who have a sensible policy for more mature drivers might be useful. In that regard I have to report that I have used LV for the last few years and have not been able to get a better quotation. They have a very good record for the quality of their service. I cannot, personally, say much for Saga.
There is no evidence that older drivers are more likely to claim.
