OP should know better than to ask this or similar questions here.
Rarely will any useful information ever be forthcoming.
Some so called experts with ‘inside info’ will tout their usual bull.
Sad people with Rolex ass-burns will come to pour scorn on you and tell you how this is pathetic, abusive blah blah.
There will be some pieces of truth in some answers but will be hard to separate the chaff from the grain.
I am no expert but I do feel the wait lists are a myth and also the allotment is random and there is no formula. Sometimes being in the right place at the right time and coming across the right sales person may make a difference.
Unfortunately there are only four ways of getting these desirable models:
1. Have a faithful purchase history with AD. Not drinks or BJ or strippers but buying what you need/want from same AD over a period of time and staying in touch. No need to chat them up or send flowers.
2. Going with a gray dealer and paying the premium
3. Spending a ton of money on what you don’t need/want in hope of getting what you need/want
4. Getting lucky.
1 and 4 are recommended. There is no exact science or formula as to the amount of wait time or amount needed to spend to get a particular model.
