I would bet that a lot of that data is pretty inaccurate. What people buy vs what people want can vary quite a bit due to how many manufacturers package items together.The automotive industry has been doing this for 60+ years. At the most basic level, you are armed with every feature and trim level every competitor offers, and the number of vehicles with those options that sell. We can also look at our reservation list for breakdowns at a high level. Beyond that, forecasting magic has to happen. In our case, we are spooling up a brand new factory and so we will start with a few simple build options and certain colors. Then we can expand offerings as production ramps up and quality remains strong. But there are always adjustments throughout the production year (called running changes).
My 2019 Pacifica is a Limited trim. It came with all sorts of options that my wife and I did not want. But Chrysler only offered memory seats in the Limited trim and above and that feature was a must have because we swap cars almost daily. Data would show that we got a power third seat vs a manual one. We didn't want that, but it's what we ended up with. Data would probably also show that most purchases option for the built in vacuum. You have to dig pretty deep to figure out that a spare tire kit is an option, but deletes the vacuum. Almost every Pacifica we saw on a 2 local lots had the vacuum. We custom ordered ours to get the spare tire.
