I dunno, I quite like it. It's not one of Alfa's best but it's far from being one of their worst. Taking off my Alfa blinkers I find the 75 (/Milano) pretty ungainly. The Mito and Giulietta are both spoiled by their front ends, the 4C is better in proportion than it is in detail, and the 8C was also sullied by an overcooked front-end.
Then there's the Arna, which is just plain dull, and the 33 which isn't that bad but hardly a stunner in standard spec. Though I'd still happily own a 33 if my garage was large enough. And while the 1970s-1980s GTV is far from ugly, I remain to be convinced that it's anything special - the Alfasud Sprint was a much prettier take on the two-door fastback thing by Alfa.
So I suppose I'd have the Giulia over all of those. And while the 159 is a more cohesive design, the spec (and weight) of the Giulia is a lot more appealing.
