The only way to avoid a sequential plate is to already have the personalized plate in hand already. Give the plate to the dealer, dealer puts them on the car, and fills out the registration form assigning the new plates to the car.
The only way to pick up a set of personalized plates is to have a vehicle to put them on. No speculative ordering.
I've transferred plates to a new car with no sequential plate assigned when trading in an old car for a new one. Dealer just transferred the plate over and deregistered the old car. This week I'm picking up a personalized plate for one of my cars (the one I'm keeping after the 3 gets delivered), and I'm gonna ask the clerk if I can abuse the system by:
1) Ordering a new set of personalized plates
2) When they come in, assign them to my current owned car, and pay the "retain interest" for the current plates coming off the car.
3) Without leaving the desk, re-assign the older personalized plate back to the car, paying the retain interest fee for the new plates and keeping them
4) Give those plates to Tesla when the M3 is delivered.
I'm sure they'll say no, but it's worth an ask.
