Particularly for those currently considering ordering and also for general interest, would be good for those of us lucky enough to have our cars to rank our various options in order of how much we rate them. Here's mine: -
1 DCC - haven't driven a non-DCC car so actually it's difficult for me to comment much other than this: in comfort mode, this is the best riding car I have ever owned. I'm 39 and have been lucky to have had my fair share of decent motors, mostly sporty to be fair, but this car does ride & handling combined, better than any of them.
2 keyless - added last minute for fear of regretting not having it and this has turned out to be one of my favourite options. It just works seamlessly and like a couple of other aspects of this car has become a 'key' option I'll be looking for on future cars

3 reversing camera - for the price probably the best £value of them all.
4 winter pack - have been suffering with my bad back last week so have already had these on and love the surface area heated, which goes down to the thighs and includes the lumbar area. Bit costly for what it is but last cold-season I used my heated seats for almost 6 months of the year, so worth it.
5 park assist - couldn't resist this at the price. Obviously gimmicky and not something I'll need to specify again but a good party trick to show your mates and should protect those gorgeous alloys when the missus is driving/parking the car

6 high beam assist - to be honest was half hoping the shambolic info around at the time that most of us were placing our orders meant that by ticking this relatively cheap option I'd actually get the much more advanced dynamic beam assist, no such luck. Fairly useless.
Although a standard feature rather than an option, I would also rank the auto distance cruise control highly. It makes for really relaxing motorwaying and I think it'll also have to be a regular feature on any future car I own.
