Don't think there are any Swiss owners on here yet.
They are different to the UK cars though, the Recaro's are covered in the same cloth as on the rear seats, and not the leather / suede that we get. I think the V6 spoiler is also an option too and not standard fit. They are numbered but obviously separate to the 500 UK models.
It was the Swiss team's choice. They prefered the seat trim and did not want the spoiler as standard. The only other difference is that the UK cars have an alarm.
