whats the difference
 

whats the differnece between 06 and 07 h2 . when ever i try and find parts its always 03-06 and the 07 are classed with the 08-09 or on there own , like i know 08 has the 6.2l (lq9 ) and the newer tranny but why is it classed with it and not with 06

No difference that I am aware of. There's two 'models' '03-07 and '08-09.

they do it to just confuse everyone!!!

Think of the 07 along with the earlier models. 08 is when the engine and tranny were improved.
