Go for the 2003.
i don't mind paying full price than $100 off a old model.
There are reasons why they make changes to a bike every year.
also if you ever want to sell your bike for another, you will get more money for the newer model.
Its really personally preference just like cars.
Do you have to have the latest car and pay msrp. Or would you rather go for the year-end closeout deals.
To me whats the point in buying a bike that came out 1 year ago. If you are going to spend money on a NEW bike spend that little extra on a real NEW bike
