00 Z24 Auto
There were only 3 engine options in 00-05
00-02 had the 2.4L Auto and Manual, 2200 Auto and Manual
02 had both of the above + Ecotec, auto and manual
03-05 were all Ecotec auto's or manuals.
So, neglecting the transmission stuff, you only have 3 models to choose from. Seriously though, like Robo said, if you got us Fuel and Spark, you'd keep most of us happy.
