The GT feels so different to a 156 even though they're basically the same (floor-pan, engine, etc)
They just feel tighter and handle better.
Don't get me wrong, the 156 and Coupe are a couple of my favourite cars, but sometimes after driving them and then a GT it just feels like I've stepped 10 years into the future.
might have to try the Gt :), although my 156 is a face lift with veloce suspension uprated to Ti speck and running wider offset GTA alloys. It does feel very solid and very tight, felt as good as my dads low miles, new 320d.
I am probably a little biased as although I prefer the alfa in a lot of ways I do miss the fact the coupe feels twice as fast and has a beautiful engine note also my coupe although having slightly less feel actually corners far faster particularly on fast roads, although it is NOT running standard suspension.
