I think it would have been more interesting to do this race as a real re-do of the 2004 race with the DB9, but with the new Vanquish. Start from Dunsfold, finish at Casino Square. Even though the train is faster now I believe James said that Jeremy won the original race by well over an hour.
I just don't understand why they did this race the way they did, especially since Willman said that they were waiting for years to have a great idea for a new race. This was really the best they could come up with? A strange premise in a boring irrelevant car?
