I have a MS 90 D built without premium upgrade package and with Multi Pattern Black seats - in the design studio they appear the same construction as the leather seats. I actually prefer the textile Seats for durability. I was considering Leather only because they came with the Next Gen Seats (reportedly more comfortable) but it appears the seats are the same in the 90d regardless of fabric choice. This is not the case for 75 or 60 models. Can anyone confirm or comment? Thanks!
