Well... Bad news chaps.
It seems the Maserati factory PR company either reads or is given the information from this forum.
They have complained to the city councils in both Modena and Carpi, 'requesting' that they withdraw permission for us to mount a 'non-approved' display in the Piazzas. Obviously the mayors have complied with this, as a few Brits/French/Germans with Maseratis older than 3 months aren't as welcome as the people who have paid the factory for the official tour. Two emails arrived within 15 minutes of each other...
In essence, this means we can't park in the Piazza in Modena, or in Carpi. Or rather, if we do there will be an almighty fine. It's not a huge problem, just a slight change to what we had planned next weekend, but I can't say I'm happy about it.
Maserati and the town of Modena in particular need to have a good long think... It's astonishingly short sighted and leaves a very nasty taste in the mouth.
