Insurance for extended trips to France?

[Beefmeister]

Morning all,

Father in law currently lives in Dubai but returning to the uk in May. Well I say that, but they'll be spending half the year at their house in France.

They've ordered a new X3 for when they return, but are struggling with the insurance side of things.

Does anyone have any tips/hints? Do they get insurance in France as well?

Thanks in advance.
