56-reg Petrol, Owner for 1 to 3 years

The Quattroporte Sport GT has been a delight to own and drive.
The feeling of being at one with a car that has so much soul is an absolute thrill, even after nearly 3 years of ownership and many continental trips it still makes the hair on the back of my neck stand up. Considering I have owned a number of ' exotics' that's high praise indeed.
