I doubt there'll be more than 20-30 sales for the rest of 2010 as the early adopters grab the cars that have already landed.
There is only a small number of cars on Irish soil already (less than fifty), with a few more trickling in. The order book isn't even open yet (no option prices have been released), and faced with a 10-12 week delivery time I guess most Irish customers will wait until after the plate change on 1. January 2011.
As for me, I never buy a car in January, and will shortly be having an expensive conversation with a plumber about bathrooms which is going to delay matters somewhat, but all going well, I expect to join the Giulietta owners sometime between March and May next year.
