For some reason, they are taking around 4 months just now, sorry.
I work in a fiat dealer and after having told a few customers 12 weeks (what they usually are) the last few factory orders I have had have been 16+ weeks.
The other problem is, the logistics have changed in the way they are "called off" from walon.
In the past, when the car got to status 45/50, we had to go online and physically request for the car to be delivered to the dealership.
Now it's an auto call off which is a pain in the arse, as all of my cars have stayed at status 40 for weeks, haven't changed to 50/60 and have appeared unexpectedly. (Status 60 is the car has arrived at the dealer)
This means you cannot give the customer an update as to when the car is due to arrive.
The whole fiat/ stobart logistics is poor at the moment, so if your dealer cannot give you a time for the car arriving, that's why.
