Toyota's inventory checker for the PDX and SEA zip codes shows roughly half of the ORP KDSS models do not have a moonroof. So KDSS without moonroof is definitely available. However, there was only 2 of my color choice in the area and both did have the moonroof. If I was dead set against it I could have (a) waited, (b) bought one in Washington or Idaho, (c) chosen a different color.
Moonroof was never an issue of contention, so it never came up in the negotiations.
Color, KDSS and price were more important, so I'm okay with the moonroof -- and I'm looking forward to testing it out with both the moonroof and the back window open at the same time.
