Ouch!
If it's the whole Caledonia group that's gone bust then that takes out several Fiat dealers in one swoop, which will be very unfortunate both for customers and for Fiat in terms of dealer coverage at such an important time for the company. Fiat could (and should) honour the order with another dealer as a goodwill gesture, and I'm sure that Fiat could stand the loss of a deposit cost for each car from its profit margin (especially for the 500) in order to keep its customers happy.
Though at least on the bright side there may be (at least) three 500's available for sale pretty soon
