what does it take to get on the list? (other than money)
Spot on! actually all the new Ferrari you got to have F12,458,FF, California plus one pre 1975 Ferrari model and alot of who you know in the factory.
The only person I know who has one on order also has a 288 GTO, 550 Barchetta, Enzo, 599 GTO, 599 Aperta, and an Italia Spider. As well as excellent connections with the factory.
There is no rule but the factory would like you to think that owning the 5 latest Ferrari's from new (not pre registered or bought for a premium) would be the key. I know a number of people getting cars that haven't had an FF or F12. One had a new Enzo and sold it for overs and is still getting an LF. connections is keys!! Knowing Luca well will pretty much do the job!! So if you haven't got one now the only way is 'money' or build a special using that running gear and chassis.
how do they know they were "rejected"? were they invited to the private showings at the factory earlier in the year?
