Could you give some more details on the car - age, when you got it, history etc? Trying to gauge if you've been unlucky or if the car is a wrongun somehow.
A warranty might be an option, but that won't help restore faith in the car and the hassle if it does go wrong.
It sounds like you have more on your plate to worry about than a car so maybe running a premium car right now isn't the way to go. Do you need a diesel?
