My vintage Vespa finally arrived in Geneva... with a little leak in the fuel pan and some other bits that need a mechanic's touch.

Can anyone recommend a good mechanic or shop that could take a look for me? The specific model of Vespa doesn't exist in Switzerland, so I'm thinking either a mechanic who's very familiar with Vespas or a vintage scooter mechanic would be ideal.

I've used Spanish and Italian to coax my former mechanics into action... and I have a little French in my pocket.
