I think the article's pretty much spot on to be honest - Alfa do have image issues to address in this country, but they are addressing them (which is why the Brera and 159 have ended up weighing as much as they do - they're built like tanks!)
Residual values of Alfas are also improving, so that's another sign that things are on the up. It'll mean that fleet managers will be more willing to add them to their company car lists in years to come, and means Alfa should start selling a lot more cars. None of us want Alfas to be as common as Mondeos or BMW 3 Series, obviously, but the more profit Alfa can make, the better it's got to be for the development of more and more interesting future models.
A lot of undeserved Alfa bashing takes place, as we all know, but I think this article paints a fairly accurate picture of how things have been over the past few decades (in the UK at least). Looking at the way Alfa are moving now, I think there's very good cause to be optimistic for Alfa's future.
