Hi
We opted for the heated windscreen. With having a little one on the way our thoughts are that any time saved on a morning will be a big help so pressing the button to quickly de-mist or remove frost will be a bonus. We were initially thinking about the boot floor but also dropped this from the order as the boot capacity is so large, we didn't see the need to have the ability to semi-reduce the space. Having had leather seats in my previous Golf, I've always chose to not get these again. This is purely personal but in the winter they're great, always comfy and easily warm with the heated seat option, however, in the summer they can get particularly hot and are hard to cool down.
Other than these, your order sounds cool. The LED front lights look amazing and will really suit the black paint colour!
