It's a problem with a lot of newer cars. I've never had a less than 5 year old vehicle that wasn't a backorder or wait on some specific body panel or lighting assembly in an accident. I think Tesla gets more press for it, but It's not that different for many modern vehicles.Still not great. Know someone with an M3P that's a year or so old, and got rear ended in a fender bender.
It took some time for the "approved" body shop to source the new bumper cover, but at least the car was driveable in the interim.
