Find it quite hilarious that leather is seen as some sort of ticket to the promised land. In another thread I speculated it was the rich corinthian smell that convinced Cadillac buyers that their $25k premium over the same car from Chevy was worth every penny...
For my Model S I specifically chose the base ("textile" as we're calling here) seats, not only for my taste but also to improve overall resale value.
How ?
1. The Tesla Model S leather seats (both kinds) don't seem to wear over time as well as leather seats in some cars, which means when I go to show my car it will have lumpy, worn leather seats. Instead, I'll be showing an interior that will be nearly showroom condition as long as I take care.
2. Seats are one of the easiest items to upgrade in-place (eg. upholstery as some have suggested) or replace outright, so if it turns out that only the Model S cars with leather are selling, then put in some leather seats, even Tesla ones from a wreck if you want. Or buy new from Tesla.
The Next Gen seats are a better fit (literally) for frequent spirited driving, though. There's no denying that, I still miss them from a loaner months back...
I get nothing but complements from the base seats eg. "wow they're comfortable" etc. Not one person yet has commented that I didn't get leather.
