I ordered an S yesterday 6/24 YAY!! and have decided on the standard seats. But, I have not been able to see them in person and sit in them at a Tesla store. Each time I visited a store they did not have a car around with the standard seats. My only concern is the seat support and whether it is any different or less cushion than the leather upgrade. I prefer not getting leather seats this time around but have a bad back and an uncomfortable seat is not an option. The obsession facilitator said he "may" have one on Tuesday so I'm going back . I have until July 1st to make any changes.
