AutoPilot Nostradamus
The seats have been confusing. At one point there was next gen, performance, nappa, and textile. But then a few days later either the perf or the nappa seats were dropped. I think performance was dropped? But now if you look it's next gen, nappa which is actually performance, and black textile.
Seats are like this:
Textile (obvious don't need to explain this)
Nappa (Same structure as textile with leather instead of cloth).
Performance (Nappa with some panels being alcantara and with a different colored piping on some edges [black seats have red, grey seats have tan and tan seats have grey]. The name performance comes from the fact that this upgraded seat was only originally available on P vehicles. Availability since then has bounced around between all vehicles and only P vehicles since.)
Next Generation (Leather Seats with more bolstering)
Performance seats have been dropped from being able to be ordered. But I believe it was possible to order Performance Seats on a P85D and I suspect that Tesla would fulfill those orders. At least one of the people in one of these threads that's reordering mentioned that mistakenly ordering Performance seats was part of his decision to reorder.
Some people with grey Nappa seats in non-P85D vehicles have been offered Performance seats instead as there has apparently been a shortage of Grey Nappa seats at the factory. This might be an attempt to eliminate inventory. P85D vehicles originally ordered with Next Generation Seats appear to be being delivered with either Nappa or Performance seats (at least I've seen people posting saying their orders were coming with Nappa or Performance seats). Also there seems to be a lot of variation as far as if all the seats (front and back match) or if only one set of seats has been swapped based on what people have been reporting.
So your spreadsheet does not appear to support all the available options or represent the situation with the seats very well. I'd suggest two columns for the delivered seats (front and back).
