1) I have seen pics of early production cars being delivered with the GM emblems on them,
so pretty sure these made it on some cars, just not sure when/if they became discontinued.
2) beige interior: I am pretty sure white or cream was not an interior option, unless you are saying the beige was in name only and looked white/cream.
I know the production was low:

BTW my Aqua blue metallic was produced 10/09 according to the door sticker, and the original owner said he ordered it right before it was a discontinued color. (Not sure how much truth there is to that statement.)
I am sure I am missing some other items that got switched mid year....
