It's one of the perils of owning/operating older vehicles, whether you put high mileages on them or just leave them sitting is that you spend your life fixing them up as stuff wears out or just ages and decays.

At one point in my life I owned seven vehicles; a van, a car and five motorbikes. I spent pretty much every weekend fixing something that had broken and at no point were all of them roadworthy at one time. I also spent a fortune on parts and fuel shuttling them around to carry out repairs and I never actually had the pleasure of using them much. Eventually I thinned the herd and bought newer cars and vans rather than getting them cheap and repairing them myself as life is too short.
