If you go to the choose my car page and select a CC with metallic paint and leather, it comes to £17200. On the french site the same car comes in at 16020 Euros (I have an old keyboard with no euros sign on). So I went to a currency converter page to see the difference in price
The french car comes out at £14400 approx, where as the UK car comes out at 24000 euros.
I didnt realise until now just how much more we pay for cars over here.
