I saw the limo one IRL, it's pretty small actually, definitely more of a handbag than a shoulder bag.
As for colors, theoretically, BV bags can come in any of their existing colors -- you just have to special order it. The price is the original price of the style plus 30 percent. A SA told me that since it's still pretty early in the season, BV has extra leather of most (if not all) colors.
