We leased a 17 I3 and plan on getting a 17 model S between now and June. I am also looking for a post 10/16 to get AP2. The only imperative option is smart air suspension as I have to transfer my wife from a wheelchair to the seat and ride height makes a big difference in the ease of transfer. We test drove the S and X in Rocklin last week and the wheelchair and service dog fit great in the S with the rear seats folded down. We are very hard on seats due to sliding in and out, dropped food, etc. The question is whether the cloth insert seats seem to wear better than the leather? From pics of used ones, it does appear the vinyl and cloth insert version wear better.
