Trueblue,
I've looked at hundreds of window stickers, and I couldn't find a rhyme or reason to them. It could be the plant they come out of?? Anyhow, some stickers show the 5600 6-speed as standard equipment, and hence it looks like it's a no charge. Make no bones about it, the 5600 costs $400 extra. When I ordered my '04. 5, I could have gotten the five speed for no charge (no thanks).
