I just think people run away with spec because having spec is perceived as 'kudos' (Reminds me of those posts you get on other forums where people post about how they have a car thats FULLY LOADED in block capitals) and end up adding things that has no real value beyond being able to tell your mates down the pub that you've got XYZ option. Things like night vision and, lets be honest here, gadgets for rear seat passengers are firmly in that bracket. Best to either save the money or spend it on other options you've neglected because they don't sound cool enough.
The comedy priced B&O audio system has to be the worst con on the F10 options list right now, I can't imagine why anyone would spec that? It's £3300 and it's car audio, it's never going to satisfy the audiophile with a high end home system and for everyone else the 900 quid Harmon Kardon system is surely a decent enough upgrade.
Ditto self park. A fantastic option worth showing your mates, a bonus if it's there on a used car but not worth your own money. Also 4 zone AC. Really? Whats the point? What real benefit is there - thats worth hundreds of pounds to you - for having the ability to allow a rear seat passenger to have a temperature that's 2c different to the temperature on the same side in the front? The 5 Series, as standard, will pump climate controlled air into the rear. It's fine, it really is.
And the TV function? Really?
Yet some of the options on the list are genuinely useful - surround view is absolutely fantastic, a huge bonus, and worth the extra 200 quid over the cost of a reversing camera. Sports Automatic transmission - the BEST £150 you will EVER spend over the cost of the regular transmission.
Heck even the leather dash at a grand will probably make more of a difference to your daily driving life than the equivalent money on random stuff instead.
