The car may have been in Switzerland since it was built, up to 2006 when it was offered for sale.
I can tell you that other than Roger's photos, these are the first images I have ever seen of the car that were not supplied by McLaren themselves. I'd be interested to hear exactly when they were taken. It must have been fairly recent as I see the current style MBZ S-Class in the background.
