I didn't really know where to put this, but I rode in my friend's Alfa Romeo 159 sedan yesterday as we went to dinner together. (Actually it belongs to his late brother, still a bit sad, the family's kept his car).
Since I'm no expert, wow the styling has held up well; didn't realise that generation ended production in 2011 but it still looks gorgeous inside and out ! I loved the brushed aluminium dash and round centre gauges. The Alfa Romeo emblem, even on the rear seats, was a nice touch.
It was just a short jaunt to the next town for dinner so he didn't drive fast or far, but judging from the automatic gearbox and petrol engine, probably the V6 version then ? (Chaosphere, you might know better....)
