If you haven't had it by now, I suspect you may be flogging a dead horse here.
The Naples factory has probably been retooled for production of the new Panda during the Italian August shutdown.
Not yet.. production is still on, they are on turns anyway and the 159 production line is working something like 1 week per month... six months is quite some time, but is much better than other car makers (16 months for a Hiunday SUV in Italy, 9 month for some german cars - don't remember if it was a Polo or a Scirocco, and many other).
I waited 4 months for my Spider... and it was still on "full" production.
Don't too hard on your dealer, I can't imagine they have any leverage over Naples, and Naples wont have told them anything.
That's nonsense (or at least it is in Italy).. Since when the order is sent the dealer can track most of the production process and report the state... They cannot force the process, but i was able to know when the order was acknowledged, when it started, when it was finished, when the car was loaded on the truck for delivery and when finally arrived on the final pickup park (Spiders need a special truck for the final delivery to the dealer, as they are a little bit lowered compared to Breras and 159, and because they are put on a specific position in order to avoid any fluid leak from the track to damage the fabric roof). I waited almost 3 week for the final delivery, but the dealer knew exactly where the car was (though had no confirmation on the exact delivery).
The dealer should be able, and should, inform the customer of the car status, i have always seen (on more than 30 cars delivered to my and friends) that if at the order a date is given, that will be the delivery date... that's at least what happened to me and my friend (lucky, maybe), and at least in Italy the dealer DO know where the car is and at what stage it is.
