Hi Andreas,
Is that AF Cars, the Aston dealership ? Are they sold-out as in closing-down, or just nothing in stock ?
Just curious, as when I lived in Switzerland in the 1970's/80's, I did a personal import (a TVR) and had the "Typenprüfung" for that car done via Heinz Kobel (probably long-since closed).
Mit freundlichen Grüßen,
Peter
