Any way to predict Forzathon Shop 599 credit car? (Not talking "Ferrari 599" cars)

So as we hurtle towards FH6, I’m trying for a second time (starting from zero cars with a different GT) to accumulate as many of the 752 cars that I can. I’m so close, yet so far away. I need about 100 cars that are in Horizon Backstage - and I realize that I will probably never be able to find the Ford Capri FE and either of the two Quartz cars in the Auction House. I can grind Forzathon points to get the backstage pass and whatever 599 credit car that shows up each week for (likely) two a week. My question is there any way to predict what the 599 credit car will be based on past Festival Playlist sequencing? Probably not, but I thought I would ask. Please don’t ban me, lol.

yes, there was a list showing cars that havent appeared in fzn shop in a while. next weeks car will either be a common car or something like the pontiac gto 65, lexus isf etc as they havent appeared often
