Well, just wasted 60 euros on a garage - needed to find out where the oil leak was coming from on the motor - they have confirmed (for 60 euros) that there is a leak and it could be from four different possible sources! When we asked how much to find out which one and to fix it, they replied they didn't know how much or how long it would take.
So...... we are now looking for an english speaking mechanic - a mobile one would be fantastic..... who could come and have a look and do the work.
Car is running fine, just don't like the oil leak on the ground all the time.
We are in Bedeille in 64.
