Strange, in my country (NL) you can order the business intense version, the one I own. It's the most upgraded version and it contains more options then the top model in the UK.
I had ordered an FR business intensse and all options (except red brake calipers and adjustable floor in the back). I had pay 5000 euro's extra for it. I think it's about the same in GBP. Totally I pay 27k for a full option 1.5 tsi.
But as I say, electric rear windows and armrest is standard in my version. Even acc and climat control. Led wasn't standard. Cost around 580,00 I remember.
I don't know why they made them different in each country. Don't sound logical to me...
