Cheers guys.
I am getting happier with the car, never did like the standard 19's, but didn't want it to not look OEM.
Nothing more to do on the exterior apart from some new B pillar trims I have sat waiting to replace the two with tiny marks on them.
Replacement of the door seal and sorting out the boot switch mean everything is done in that department.
Chassis wise I have now done all the front end, thrust arms (with powerflex bushes), new lower control arms and had a full 4 wheel alignment done.
Still not happy with the amount of rear camber as its eating rear tyres so I am going to check the rear wishbones, but also look at options for camber adjustment.
Will also do the rear subframe bushes at some point, before they start deteriorating.
Engine wise, I have just done a full service, plugs, oil, filters etc.. but the nicest thing to have done was the rocker cover gaskets which has been on my mind for a while since I did the PCV hoses.
Slowly working my way through the "common" X5 issues, mostly before they become an issue which I prefer.
