What's the used Maserati Quattroporte saloon like?
It's a proper Italian luxury car. On the open road, there's masses of grip and good body control. However, the car lets itself down a bit on twisty roads and rough surfaces, where the ride can get quite fidgety.
It's quiet in the cabin most of the time, but the lovely sound of the V8 engine does creep in when you push it hard. Still, that's no more than you'd want.
