I did search and couldnt find anything for the x150 on this forum...whereas it's a sticky on the X100 forum (see link below)

https://www.jaguarforums.com/forum/xk8-xkr-x100-17/xk8-xkrxk8-xkr-non-oem-interchangable-parts-thread-11

This can be anything from wheel nuts, brakes through to transmission and engine parts...& lets not forget interior trim items that are sometimes a pita to source from main dealers or scrap scrap/salvage yards.

Hopefully, when we've got few dozen definitive posts, it can be made a sticky as it is on the X150's predecessor.

Also your collective experiences will save other members a few £, € or $
