As others have said, it's a great spec.
Nobody has mentioned the storage pack, for £70, I think it's really good value. You get under seat drawers as well as luggage nets under the parcel shelf but the drawers are a boon. They're very discreet and about the size of a shoe box, maybe 20% lower. It's easy to tuck in a 230v power inverter or sat nav and they're rated to 20kg although I think you'd have to pour concrete in to reach that sort of weight! The arm rest stow away is a design wonderment, I think you can store a pen in there and maybe a pack of chewing gum if you're lucky so the drawers actually compensate for the lack of storage in the centre column.
The parking camera is fun, don't get me wrong but I live in London and having a kerb side mirror that automatically drops when I reverse in (99% of the time) is far more valuable as a tool when paired with parking sensors and it's a lot more cost effective.
Regarding your VAT issue, HMRC recognise VAT under 'time of supply'. I won't bore everyone with tax concepts but there are guidance notes for businesses available on HMRC [http://bit.ly/bpkWDJ] and that should clarify your position regarding paying that extra 2.5%.
Hope this helps and don't forget to post pictures when it arrives.
