As a recently adopted Alfisti, and being my first in 26 consecutive cars, I think I can be a little more objective than some...
Referring to looks is daft when discussing recommendations. Anyone can see they look great - it's the living. driving and owning experience that needs evaluation.
I'm pleased with mine, but doubt I shall replace it with another in 3 years time. It's great having the exclusivity, but it feels like a dated design to drive. Cruise control in crazy position, and switchgear very flimsy feeling. Oddment storage pitiful (and I know you don't buy an Alfa for such things). Handling/performance does not live up to the Ti image. Truly shocking economy. Any high speed refinement obliterated by wind noise (and I've had the seals replaced). Will need a respray at 12 months owing to stone chipping.
Build quality good, but doors do not shut like a BM/Merc. Seats unsupportive. Windscreen wipers complete crap (and have been replaced). Gearchange still to loosen up, and if it doesn't, is notchy and obstructive.
Huge pleasure can be had from the rarity value and looks. And it's not a bad car - just not as complete a package as a 3 series or C class (but cheaper). I'm sure it's a lot less flaky/flawed than Alfas of old which is why long standing enthusiasts see it as such a triumph.
After driving my 35 year old Fulvia for a day, the GTi used to feel like a leap of generations rather than decades. The 159 not quite so.
I would recommend it as an overall package, but if it's pure driving experience you're after, I'd say go German.
