I am considering maybe moving my confirmed order of a 5 seater X 75D to a S given the following observations I have gathered in these forums: First let me say that my first sighting of a model X was yesterday at a supercharger but did not get to check it out. -The 5 seater X 75D delivery is probably end of the year at best! - The middle row does not fold down (does on model S?); many people are mentioning there is more room in the S. -X and S seem to have the same ground clearance. I assumed that the X was more of an SUV but that does not seem to be the case. I did order SAS but the S can have that too. I have quite a lot of use to get stuff from hardware stores into the back of the car and I end up folding middle row seats all the time. Am I missing something?
