04 vs 06

[evomind2]

for anyone who has driven both models, how would u compare and contrast them?
i know the 06 uses a different engine and trans, but is it worth the extra dough?
i can get an 04 this spring, but if i stretch, i can swing a used 06 POSSIBLY by fall.
not sure if its worth the extra cash.
i would imagine the 06 with the 5 spd trans is a better highway vehicle...
can the 04 be retro fitted with the 5 spd trans?
thoughts/comments?
