Alfa Romeo 159 reliable?!

Hey guys, I’m thinking about getting an Alfa Romeo 159 because I like it visually and, depending on the motorization, makes a sporty impression. Since I don’t want to go to the workshop all the time, it would be great if the thing were also reasonably confident. What about it? Does someone have experiences would be great if they could share them, and of course if the assessment with the sportiness is true.
