Talking to a Ford dealer recently, and he wasn't impressed with the second plate at all: said it has turned May and June into no-sales months. July, which used to be the worst month of the year, has picked up a bit, but the recent gains in sales have been January, not July. Maybe it's too early to tell yet, but it seems Irish people still want the "new car in the new year".
For Alfa, we'll see a few new registrations in July as the MY2014 dealer demonstrators are registered. With no test-drives until July, though, any new deliveries won't arrive until September at the earliest.
Incidentally, I noticed Dan Seamans (Cork Alfa) had the builders in at the weekend... looked like showroom renovations.
