Thanks Simon, that all makes sense now, I know where to come when I decide to do a refurb. In your experience how many miles do the generally last before needing refurbishment?
Which bit?

Wishbones and rose joints. I have a little bit of creaking from the rear passenger side, need to investigate if this is rose(s) that are worn. My car has only done 20K so would have thought it would still be OK, I doubt its had any serious punishment, apart from me

, and my Rosie in Blue likes a good spanning.
I had a few front bottom ball joints that were replaced under warranty or at very low mileages, mostly NS as those take more of a beating from drain covers etc near the kerb.
Most of the rod ends are protected by rubber boots, so should last quite well, however, should the boot have been damaged at some point then its anyone's guess how long they will last.
Again with the wishbones, I don't know the mileages involved on the cracked, or damaged ones I've seen, but road dirt hides the cracks very well until they become terminal....
Creaky rears, could be rod ends, but more than likely damper/coilover , possibly bent lower wishbone or inboard spherical joints.
The entire rear subframe has to come out to change anything inboard....
Not the work of a moment.
