to admit that I stupidly scrapped the files on our french vehicles a few months ago (after moving back.) A lesson for others!
Luckily our CA/Pacifica agent in France is very helpful and she sent me a copy of the last statement before we sold that car.
We're trying to get a cheaper estimate for car insurance here.
Another point is that the UK insurers seem to prefer that we have UK driving licenses, so we're in the process of changing now. Although legally I think we can drive on a french license for 3 years after leaving France. But post Brexit, who knows?
