first of all the db9 isn't neccessarily built for speed...it will be out performed off the line by many tuned japs like a skyline or a supra...heck even the exhaust is artificial,as gorgeous as it may sound...
but i doubt any jap can have the beauty and the presence the db9 has...that's what the owners here paid for,to be seen in a db9,to be heard in a db9,for the admiring looks you get...and most of all for the feeling of knowing that you own an aston martin.
