Try ADAC the German breakdown company. You are covered, not the vehicle so whatever you are driving you will be fine. If you go for the whole "Partner PLus" package you and your wife/partner and children are covered for medical emergency, repatriation (with a driver if needed) and all sorts of other items.
Be aware the most they will pay for a breakdown that requires as tow to a garage is @200 and if you are in FRance you will have to pay and then claim it back from ADAC.
They do have a good reputation although therehas been some negative feedback on other forums, this is balanced by some good. I am a member but havn't needed to call them so I went with them on recommenation alone. Have a look at their website which a google search will find, there is an English section you can read up on.
