Just read this SR.
If the fuel bill and hauling adults in the back aren't issues, then you really can't go past a 3.2 Brera.
Personally, I don't think the 159 saloon can touch it in the style stakes, as much as I love the sedan. Heads will turn.
Stunning vehicle, lovely V6 burble and very composed on the road.
Agree with others though that having a few doubts probably isn't the best sign.
I know I was completely smitten the first time I saw and drove mine. Over 12 months on, nothing has changed.
Love the look of a well maintained Brera in red. Great colour.
Good luck with whatever you choose to do.
