If I were to find a very low mileage XF (not SRT5) being parted out, what parts would you recommend I glean? It needs to be parts easy to remove, and worth having around.

Obviously I can't grab everything, and the main issue my car is having now is a sticky ignition, which I think would be too time consuming to remove. I'm looking for easy stuff.

Depending on the prices, I was thinking of spares for some of the sensors and control modules, since I think they are mostly easy to get to. I'm not completely sure where all this is located, I'm still learning.
But generally:

RCM
crankshaft position sensor and bolt
camshaft position sensor
central locking pump module
security control module

What do you think?

I know the risk of storing too many spare parts. I have a bunch of parts for my MiniCooper S that was totaled 2 years ago; haven't gotten around to selling them yet. So I need to exercise restraint

I'm interested in your comments, thanks
