I went with an Infiniti Q50 Redsport because it has 400 HP and is very fast, faster than the Alfa. But the Alfa handles and corners better and is way more unique and stylish. Every time I see one (which isn't often) I have second thoughts.
It's true that reliability is an ongoing issue with Alfa Romeos in general, but most of the reliability issues reported by the car magazines in their long-term testing have to do with the Quadrifoglio. The base Giulia and Giulia TI have been more reliable generally.
Here's another really important issue: these cars are not selling, so you can get excellent deals. I would have pulled the trigger if the deals they are offering now were being offered then (1.5 years ago). I hope you buy one
