Wilson,
Thanks to brexit things are tightening up, if you are uk resident you can only spend 90 days in 180 in the eu, so most insurance will follow suit. There are exceptions but good luck finding one for a 3w, I found a 12 month broker but he wouldn’t touch the 3w.
Apparently a uk car is allowed to stay in France for up to a year, (remaining road legal in the uk), but not it’s uk owner!
My french insurance (3w now french registered) is about 600€ and in the small print it states over 35k value it must be garaged and have an immobiliser!
I read recently of a brit with a carte de sejour ( so obviously a french resident) driving his uk registered car from Plymouth ferry into France, french customs noticed and asked if he was importing the car as he is not allowed to own a uk car.
