Year by year changes

[fishguy1123]

Just wondered if there is a way to list the major differences between model yrs? If it's already been done how do we find it? I guess I'm mostly reffering to engine/drive train but whatever makes sence.

Nice idea, it cold take a lot of research to find that out. I do know that there was a major engine output change in 06 along with the stabiltrak being added.
