I am in the market to buy 3 used of and one new Raptor. I am combing through the net and this site and am not having any real luck finding the differences between the years. I watched some video reviews and read lots of written reviews and it seems that from 2001-2005 there were NO changes? I fnd that hard to swallow. Also other than shocks, I find no change in the 2006-2012? Does anyone have a definative list by year that shows each change made to each model?
