I bought a Eos Lux in the US last November. As you probably know, in the US, the cars are almost fully equipped and there are only a few options (like Nav.) The list price was about $35,0000 or in BP, about 17,550.
I realize that your prices get jacked up by VAT, but at 10% that would only be another 1,750 pounds. Sounds like there may be some extra business taxes, but even so, your dealers must be doing very well indeed!
