I've just put my car through the MOT and had to pay out to get some work done. On the advisory it says that there is an oil leak. The man at the garage told me that it is only minor and to take the car in perhaps next month. I have a Citroen Xsarra Picasso (10 years old) - haven't spoken about the cost yet, but can somebody please give me some advice as to how much I am possibly thinking about paying out for a minor oil leak? Thank you.
