Do you know what place you are on the waiting list? Unfortunately if you placed your order in late Dec ‘22 I suspect there are plenty of people in front of you
I’d ask your dealer how many M2 allocations they are getting per month and then try to use that to take a guess at when your allocation will come (though allocations per month is sure to ramp up in 6-12 months)
In another thread someone from Seattle mentioned that BMW of Seattle has 28 or so people on their waiting list and they are expecting only 1-2 allocations per month. So most of them won’t have it by the end of summer.
Waiting list size and allocations will vary by dealership but I presume they increase and decrease together.
