After a loooonnngggg wait, I finally took delivery of my LR white/white/photon M3 yesterday! Delivery was ok - I had to wait about 15-20 minutes while they printed out some documents, and the car wasn't cleaned very well. But overall it was pretty quick and painless.
I did a reasonably thorough inspection and didn't find any reportable issues. The LED strips are well aligned on the driver's side, and a little off on the passenger side, but not enough to bother me. Coming from a 2020 LR model 3, this car feels really well built. When you close the doors it just sounds solid, compared to my old car which sounded a bit hollow. The turn signal buttons take a little while to get used to, but I'm pretty comfortable with it after ~24hrs and I don't find myself reaching for the non-existent stalk! As has been mentioned before, these buttons don't work 100% of the time, and are a bit sensitive to where you apply pressure. I think my only complaint would be with the glovebox. It looks/feels/sounds very cheap, and it's next to impossible to fit my hand in there enough to access the USB port.
And FWIW, I did get another free FSD monthlong trial on the new car, even though I had that on my previous car as well.
Overall I'm glad I waited and didn't cancel out of frustration. Good luck to all of those who are still waiting - I sincerely hope the VIN gods smile on you soon!
