In my opinion unless the 1.9 has a heavy remap and turbo upgrade it is just too slow in this car. Even the 2.4 feels a bit sluggish but is stunning once remapped.
the V6 is a fantastic engine. The 2.4 diesel is great when remapped. The 1750 turbo TBI is very good and very tuneable.
The post 2008 only applies to the 2.4 diesel when a much better turbo was fitted. It is easy to tell because on the drivers door pillar is a plate showing either 200 or 210bhp. The 210 has the better turbo.
The weak spot slowly being discovered is that the M40 gearbox is immensely strong but the M32 (I think that is what it is designated) that is fitted to the lower power cars is quite weak with a number now failing at relatively low mileage.
General faults
Front subframes are known to rust. Some do some don't. Clean, check and treat.
Rear springs can break.
Front top wishbones bushes fail. (Cheap and easy.)
Bottom wishbone rear bushes fail. (Easy but more expensive than the top ones.)
Disinfectant smell with aircon switched on means the wiring connector on the controller is arching and burning the plastic. (Simple fix.)
Blue and Me is unreliable so get the owner to demonstrate it fully working with their phone. Hundreds of these now broken and won't be a simple fix that the owner tells you it is.
Mine has been incredibly reliable.

Under the skin the 159 and Brera are effectively the same car.
