Rolls-Royce Silver Ghost model cars

The following is not meant to be critical but to suggest. Why Does franklin mint only sell 1/24 scale early 1900s RRSilver Ghost no 1/18 is it that they have no suppliers that can make them 1/18. Right now they have a monopoly on these models. I am using all of Dennis Adler’s upper level color books. 100% of the time for every one I look 1/18 scale 2 things happen either not available or it’e Only in Franklin 1/24 scale monopoly. I am not cheat as I just bought from Mint Model the 1966 Ferrari 21 beat by Ford at Le Mans for $285 dollars and it’s stunning. Nothing against Kyushu above with the right scale I want but $400-$500 for modern era Rolls Royce. Something is wrong here. I realize there are 100s of thousands of world wide collectors. My collection is only maybe 25 Cars but growing. Finally there are tons of buyers and limited sellers and resources. Lets all get in this forum and have some great fun. Cheers George!
