Thats because when you talk about a commodore or a falcon,
your really talking about a mass produced quick slap together.
I used to own a VS Statesman V6, me and my dad pulled the
motor and box out of it and converted it to manual, it was the
only manual stato i had heard of at the time, there may be more
around now though... I must admit though, when i had that car
i loved it to death, i still regret selling it actually. Good luck with the
ride dude, its a nice one.
