Is nobody worried about resale values, in terms of leather vs. textile? I've owned a few Mercs in my time, and the one thing I learnt was that a Merc without leather and Comand (nav and other media stuff) would really suffer with the residual values. I assume since the Model S is going up against the premium brands (Merc, Audi, BMW etc) that a similar argument would apply?
Leather has its place (our other car is the kid carrier, and textile seats in that would be a tragic mistake), but I tend to agree with others here, leather is not always ideal. My current car has microfiber seats with leather bolsters, and that seems to be a good balance.
