I have a 2017 S with the ventilated seats. And then I sat in the new X with the cooled seats. Wow. Much better.We were all set to buy the Y and then my wife sat in a new customer’s MX. The MX is the only option in the Tesla line for us. Plus, I already bought the floor mats. Neither one of us were fans of the MY seats. A bit narrow ,short on thigh support and no cool seat ventilation for the hot humid days in the south.
