I would be grateful for informed opinions on the question below. I know the general area has been touched on many times, but I cannot find a clear answer! I am NOT a resident of France – we live in the UK (have a house and receive my pension there etc etc), but we do have a "maison secondaire" in the Var, which we and the family use for breaks and holidays, probably in total around 3-4 months each year. We have an (old) English registered car which we use in France for around 9-10 months each year, bringing it back to the UK for 2-3 months in the winter for MOT etc. For most of the time in France it is parked in an airport car park between our visits. The car is taxed and MOT'd in the UK, but insured in France (through an agency in Beaune with AXA France) – which, being a policy from an EU country, also gives me (minimum) cover for when I bring it back to the UK. The agency tells me that, from the insurance point of view, there is no need to register the car in France, that I can continue this for as many years as I wish, and indeed they have renewed the policy year-on-year quite happily. My question is: Is this "legal"? – or am I liable to problems in France if either the police or other authorities stop me, or from the insurance point of view if I have an accident there?
