There's an active Yahoo group for Alfa owners. I don't think there's a lot of fence-sitters on Alfas opinion-wise. There are definitely some issues they can have; you have to decide if the features are worth it to you.
We liked them a lot (although we were only looking at 2002-2004 models because of budget), but we ended up going with a different orphan brand in the end that seemed more conventional and yet had most of the features (roominess, light colored interior, lots of windows) that the Alfa had.
