Just some first few day ownership tips:
Check everything is OK and get them sorted sooner rather than later.
Watch the wheels as they have a protruding face. Most alloys are relatively flat so if you are not used to it, they could catch you out.
If you want to get some protection on wax / film or otherwise do it sooner rather than later
Paint those brake disc hubs where there is no contact on the pads. Easier now to prevent the rust than sanding down and painting over.
Choose your run in procedure. Either warm up and drive her like you hate her or follow the manual. Once done, you will not be able to change it.
Get your name onto a Seat Track / ESP day as it is very enlightening, plus you get to rag the nuts off one that is not your own.
And most importantly:
Smile.
