I think for the next couple of month, the sales numbers will be tinted by the old models clearance sale.
Elantra is going on now, the Focus will be next and then the Civic. After all heavily discounted old models are gone, we can see the new order.
How is Cruze a sales dud, in Canada or US, it's hard to understand; by the relative numbers that is. It's not #1, but far from a dud.
