I don't remember if it was Ferrari or some other Italian supercar maker, but a recent article I read suggested a buyer had to submit an application to buy one so the seller could do a background check on the buyer..
Top tier Ferraris, management is going to decide if they will sell to you, regardless of your net worth. Mid level Ferraris, if first time customer, you must buy a used Ferrari, or bottom tier new (Roma) and drive for a couple of years, then come back for that new mid tier car.
Thanks
