Personally I don't see the point of the camera AND park assist, I'd go for one or the other. I really like park assist and works a treat. It's really cheap (I wouldn't have bothered if it was over £300) and has the benfit of adding side sensors too, which can be handy it you've not noticed a low bollard etc. People will always have the argument 'I can park myself', but that's missig the point. I can cadence brake, but I'm glad I have ABS. I can drive at a constant speed, but I'm glad I have cruise...the comparisons continue.
As with regats to the nav, I just don't get it. Less functionality than my TomTom on my iPhone 6 and the traffic management is inferior. Maybe if it was half the price and had decent traffic then I might consider it.
The winter pack is nice to have, but pricey for what it is. I also had keyless as I wanted a start button, childish I know, but in a car with so much nice tech it seems a little archaic that you have a 'traditional' ignition key and barrel.
At the end of the day options add very little value come resale time, so plump for what you want and will find useful.
Just my two pence worth
