When I was shopping for my premium plus in platinum quartz, the websites showed six available across 3 different dealers, two at each. The car with the options I wanted showed as in transit for about 10 days before I called and inquired about it.
Two of the cars sold the weekend before I could go look at them. This was off the dealer lot farthest from where I live but closest to where I work. So I test drove a car from the lot where I purchased my previous CX 5. I had called the third lot that morning to inquire about the car in transit and they said it had just been delivered a few days ago and was available. I went over there the next day with the offer from the second dealer and they beat it so I signed the papers that day. They even drove the car up so I could at least see it before picking it up on Thursday. It still had the shipping plastic covering it.
