French Insurance
We were lucky. We found a French insurance company in Callac near where we have a place in central Brittany where they speak (and write) good English. We got insurance for our R4 for third party, fire, theft, glass and breakdown including courtesy vehicle for about 230 euros for the year last Easter. They just needed to sight my UK no claims (letter from UK insurance sufficed) and the vehicles Carte Grise. The insurance is valid for 90 days in any EU country outside France per trip (per trip - you are supposed return to France for at least a month between trips!).
I know you have arranged temporary insurance, but the above may be of interest to others who read the thread.
I much prefer the French system - you have to display on the windscreen a disc showing the CT is current and another disc showing you have current insurance which is good. Easy to spot 'illegal' motors. There is no road tax, it's all in the fuel price and fuel is STILL cheaper than in the UK. The only thing I don't like is that you have to carry the current CT, carte grise and insurance certificate in the vehicle at all times in case plod wants to see it. Fine, but if anyone steals the car.......................... Perhaps the French don't go round nicking cars the way they do here, they seem so much more civilised and trusting than us. Like where in the UK could you leave your car, with the radio on, the window open and the keys in the ignition whilst you sat and drank coffee in the village bar for an hour and return to find your car still there as happened in our village last year? Here it would be long gone.
Good Luck, Chris.
