You should have taken the $1500. Sorry to say, sympathy will probably be a little hard to come by on this forum. An Alfa Romeo of any vintage is not a great choice for most single-car households unless your need for a working car is very flexible. These are semi-exotic cars with typical Italian build quality (not great).
I'm not saying these newer Alfas don't have issues that the dealers (and the brand) need to fix. I was driving the new Alfa Stelvio with 2200 miles on it the other day. At a stop light on an incline, pushed the gas... car didn't do anything and began rolling backwards downhill and all interior electronics went dead. Two seconds later, car worked normally again.
It's an Alfa.
