For me the definition of vintage can change, sometime it depends on who you are riding with... One group I ride with is mostly younger 18 - mid 20's, to them my 2000 KTM is a vintage bike. Another group, 35-60 year olds, my KTM is practically new... So vintage can be in the eye of the beholder...
For me a 2000 is not a vintage bike, its the perfect bike for me... Sure I'd like to have a new 2011 6 speed KTM 300 XC, but finances dictate I keep the old girl. She may be getting older, but she does everything I ask of her, but best of all she doesn't cost me anything.
