You work in a garage don't you? I know techs who run old diesel 106' or fiestas which they never do any work on and use barely any fuel. Sounds like you're just making lame excuses to cling on to the fabia. If I had to choose between property or an ever depreciating lump of metal I'd go with a pile of bricks all day long. Guess it's all about priorities.
