I had a 156 (Red) twinspark bought it cheap fsh due to the stigma of Alfas from the 80’s still scaring folk. Loved it….then bought a French euro box diesel which I had for over 6 years, reliable but boring after the 156.
I am back in the Alfa ownership group again after buying an Alfa 159 Ti Sportwagon 2.4 jtdm nearly 2 years ago , yes its diesel but its still a good looker, sits aggressively on the road and has plenty of poke if needed or cruises like a GT along motorways. I have had bits n pieces done on it by an Alfa Specialist at reasonable costs if honest including a few modifications like Powerflex bushes in lower arms which sorts some of the wear issues and sharpens up the steering. I like it its a V5 engine and sounds great under acceleration for a diesel with bags of torque (had a mild remap done too helped the power band).
I say go for it, lifes too short for being sensible ;-)
