I don't see a need for separate forums distinguishing model years. Then XOC would look like this...

2000 Drivetrain
2000 General
2000 Performance
2000 Suspension
etc

2001 Drivetrain
2001 General
2001 Performance
2001 Suspension
etc

2002 Drivetrain
2002 General
2002 Performance
2002 Suspension
etc

........ you get the picture......

I think the following is a more streamlined and user friendly forum format.

Drivetrain
General
Performance
Suspension
etc

The super specific forums are not needed - if everyone just worded their questions/comments carefully with an appropriate title.
