Hi and welcome to the forum.
Lovely looking Z4 - bi-colour heated M-Sport seats and extended leather must be pretty rare in a 2.0i - well done!
Refurb of those 108 wheels won't be cheap as to get a proper job the rims have to be split. You can save a bit if you split them yourself, but from what I've read it isn't often straightforward. :roll:
Nobody has mentioned the roof motor yet! They tend to get wet where BMW located them, so getting it moved into the boot prevents issues. There are a few forum members that can do that for you, depending where you are.
ZHP gear-knob is definitely an improvement - just be careful getting the old one off! It can result in injury to areas you don't want injured!
Good to see you seem to have contracted Zed-itis already. :lol:
