I ve seen the new 166 in real and its a beautiful car. It could be a bit more agressive though, the headlights could be a bit more "angry", like the pre-facelift 156.
The biggest success imo is that it looks very good without having a 147-ish nose. I m against family look, i think that each Alfa model should have its own character, but keeping some characteristic details that give the factory stamp, like the vertical grill and the nerves on the bonnet. I hate it when all models have almost the same headlights, bumpers etc..
