I've had the 159 since Christmas and have yet to hear
a single person make an admiring comment about it.
It gets compared to the Brera all the time and
although you can give 4 people a lift in it,
it's practicality is not what gets mentioned.
Also, fit 'n' finish is slightly worse, even taking into account
it's a lower spec car.
The only two redeeming features are the excellent, excellent 1750TBi
engine and the opening sunroof.
Otherwise it is not a car I would advise Brera owners to switch to unless
they really have to. It reminds you too much of what you've given up.
