I love the look of leather, I just cannot stand it in the southern summer heat (even with Ceramic window tint).
I swapped the M2 Leather seats\door cards for the
M-Sport Hexagon Anthracite Cloth\Alcantara interior that comes standard in a 2-series outside the US. Bolts right up without issues; though I had to swap all the electronics over, including swap passenger seat cover from one cushion to the other as Euro Occupancy sensor is way different than the US one (even though it uses the same plug).
Entire swap (including un-upholstering and re-upholstering for the passenger occupancy sensor) took about 5 hours.
The "Estoril Blue like" stitching color is very vibrant under the light. However, there's an obvious difference when comparing it with Polar Blue stitching (Shift\brake boot and center arm-rest). I'll eventually get those stitching matched.
The US Passenger Occupancy sensor pictured I got from a junk yard, but it was no good (i think it had been rained on or something), so I just swapped skins from one cushion to the other instead. Just FYI, that sensor is "GLUED" onto the seat. No easy task to get it off.
