If performance is the top priority then buy a 997. I would not wait for 2008 as who knows what Porsche will change if anything. I haven't seen anything in writting that says Porsche will make a change to the car in 2008. I know a lot of people think the 2008 will have the 997TT front end but who knows. I like the look of my 2006 997 so I see no value in a 2008 if they do change the front. Now if performance is not the top priority I would drive the vantage and see what you like. I have not driven one but I sure like the way it looks. Good luck with your decision.
