I spotted a Quattroporte at my local Ferrari dealer while placing an order for the F430 this week. It looks much nicer in the flesh than in the pictures, so much so that I'm thinking of trading my Mercedes. Has anyone here any experiences with the car to share, both good and bad? My biggest concerns are resale value, quality and a lack of easily accesible power from the Maserati. I am comparing the car to a 4 month old S600, so straight line performance isn't even going to be in the same league, but being outweighed by superior dynamics. I am looking to keep the car for at least two years, so I don't want it falling apart after 6 months.
