Of course marketing and manufacturing people in the company have those numbers, and there is probably a way for dealers to ask for it. However, automakers generally don't publish information to that level of detail. I'd be happy to be proven wrong, but I challenge you to find the number manufactured of a certain color for any major automaker.
It's not that hard... I'm using this as a reference because when I had one I knew how rare they were... Its for the Isuzu VehiCross, but the info is commonly available for discontinued models, Like the R53. Sometimes it's as easy as a Wikipedia search. (On a side note the VehiCross I had was one of only 200 in the USA made in the Proton Yellow, and only one of 75 that color without a sunroof. ) Sent from my iPhone using Tapatalk
