Car Insurance in france (Lyon)

Hello everybody who has his car insured in France, I would be thankful for advise about car insurances in France. I took my new car from Germany here and need now for the next year a fully comprehensive insurance. I do not know nothing about insurances in France and I am afraid that they will charge much money and give no service. Does anybody has experiences with Carrefour insurances? i have got my appartement insured there. I do speak French so I could figure out the details. It has only to be more or less trustworthy ;-) (my last 2 car insurances went bankrupt and did not give the money back)
I am grateful for any help offered or just advise.
Thanks,
sincerely,
Alexandra
