that is pretty cool, i was just checking one out yesterday. i'm not a fan of how the dashboard is, but overall a pretty sweet car.
Cool vid - looks like one of the v-max events in the UK. I love all the current Astons and I'm surprised anyone isn't a fan of the dashboard - I love it (although that 'power beauty soul' thing when you turn on the ignition is pretty naff).
The top speed for the DB9 should be 186mph. I think that 173mph is as fast as it could get on that straight, needs to be much longer to get to top speed. At that speed, it slowly creeps up there.
