I would bet on the dealer being pretty up front. They aren't reported to have stopped ordering X5s for stock, they are just moving to the close out model configurations, what they call the executive edition. With the E46 sedans, those models ran for at least six months, while they cleaned the inventory out of the system. At the end of the E46 cycle, there were 3 colours available.

I think the ordering cycle in the UK is quite a bit longer, partly due to shipping time and partly due to the wait for the 3.0D

Realize also that this is BMW CA, not BMWNA, which has different configurations and ordering rules. Canada has a smaller market and they help the dealer with the inventory management challenges related to that smaller market.
