I'd love to know how many of these are direct from Maranello and how many of these are second hand. Ferrari doesn't sell directly to anyone unless you have a "relationship" with them. New models are highly restricted, it's not like you can just walk into a showroom so you can buy one even if you have all the money.
Is that true for all models? Even the “cheap”, mass produced ones?
More or less only for the high end models. Basically you apply for a model through the dealership > they send it to Italy where they accept it or not. If they do not they will usually offer you a lesser model first as you said. If they do then you get your car but you also have to sign a contract with them that they always have 1st call if you ever want to sell your car (if you break that they will never sell you again).
You can absolutely walk into a showroom and buy one. Not a rare model but you could walk in with no relationship and buy a 296 now.
I'd suspect many of them are - almost all go through new jersey if I remember correctly - with many going to Ferrari North America (FNA)
