Odd article as I can’t think of a single BMW model that has anything near 10 trim levels.
In germany they do.
Not necessarily 10, but the 1series already has 6, the X1 5 etc.
Prior: SEAT Ateca Xcellence Lux 1.5 TSI DSG MY19, VW Golf GTE PHEV DSG MY23
Current: Hyundai Ioniq 6 Ultimate
Next: we'll see what's available in 2028.
