I went through the options list on the F31 and I just couldn't stomach the final cost. Came to over £47k. Many of the good toys are just luxuries, not essential but good to have. It is what got me looking again at nearly new high specced 5-series.
That allowed me to get all the toys, virtually for free, as we know most options don't enhance the nearly new value by much.
I'm a private buyer not tied to a budget or tax implications. So I was able to get the car I really wanted, all the toys I'd have specced, without breaking the bank, (far less than the new F31 cost). Or reaching that 'bulking feeling' where I would start writing off the options, as I couldn't (in my own mind) justify them as necessary.
