The end is nigh!

I think my 13/60 estate is finally in its death throws. I had a very interesting trip into work this morning on appoximately 3 1/2 cylinders. It was never very powerful on 4 cylinders to be honest, so anything less is a bit of a joke! Got to make the decision now, slap another engine in or walk away? It's MOT is due so it could get more complicated than the engine, and there are so many more tempting projects waiting in the wings here that the decision will be a tough one. Trouble is Iv'e grown quite attached to the old shed, I wonder if I could squeeze another year out of it?
