Hi Cees,
a couple of ideas... In Milan, Luca Meroni (a Pagoda fan many of you know...he's got 4-5 of them) works closely with the garage of Enrico Pighetti, an old-school mechanic who basically deals only with older MB, and in particular Pagodas... at any time you may find a number of them in his garage for servicing..
However, the area is not so beautiful and green as Blacklick (judging from the pictures)..as Enrico's garage is in the outskirts of Milan.
Alternatively we may ask the guys in Geneva if there is a garage they know... my house (in Chautagne, 50kms from Geneva, on Lac de Bourget) has plenty of space in the garden for the cars, but no tools for mechanics!
Let's continue the brainstorming...
Cheers, ennio
