Fair play for being brave enough...
A good mate of mine had an FQ300 '03 plate back in 2005. Had a great tour through Europe with him in that car - as everyone else has said - it attracts a lot of attention.
Awesome sounding car - remember driving it on the autostradas - the way it could just tear up the tarmac was unreal, and on the Stelvio pass it was great fun.
As said - petrol and servicing costs are the main issue. Not sure what insurance is like, but if I were to have one - I'd want a garage, tracker, and to live out in the sticks somewhere..
