I can never see the point of buying low mileage cars for silly money. That one's still done 30k so it's not like it's in totally as new condition, and if you drive it, it'll just become another used S8.
Another vote for spending £3k and keep the rest for beer & hookers.
I guess... It just struck my fancy... I am actually on the hunt for a replacement for the X-Type and a new shape S8 is high on the list so I saw this while hunting!
