A lot of spares or repairs are going for that kind of money ? , but it's a case of it sounds like the head gasket with the expansion bottle but what else could be wrong with it ? Father sitting that long as we all know rust eats like crazy on the B's

, that's why mine will be getting sold soon, a few niggles but back to the one your looking at !, it costs nothing to look at it as long as your not travelling miles, and then if it was not to bad you have lost nothing as I'm sure you could sell it or some of the bits then scrap the rest so not loseing your money.but it again depends if you have somewhere to stand it ?, sorry if I have waffled on but that's my opinion
