The Ghibli S Grandsport with 430bhp and 580nm could be a contender for the 550i? Maserati got their new engines from Ferrari and it feels like it! Maybe it is down tuned a little, we have seen better number on the Alfa Giulia. Nerveless the car feels good, like old school with focus on steering feedback and sound.
The Interior is good, proaly Maserati Got one of the best leather out there. Super soft and colors are rich, smell is impeccable. Infotainment system got apple car play and android auto but it is less sophisticated than the BMW 5 series.
Cool Thing the customization for Driving Dynamics are there. Unlike most companies the buttons on the central console are still manual and easy to reach and operate.
