I declined two offers from Tesla to get a discount on a 6 seat Model X version. They made those offers prior to the end of September, when Tesla was busy pumping up the third quarter sales figures. In the first week of October, once Tesla's motivation to pump third quarter sales figures ended, I advised my delivery specialist to let me know if the 5 seat Model X would not have folding rear seats, and that if it did not, I would consider switching to the 6 seat version. That was another attempt to get a useful answer about the folding seats, not an attempt to switch to 6 seats. Since the delivery specialist did not take the bait I offered and recommend that I switch to the 6 seat version, I take that as another subtle confirmation that the 5 seat version has folding rear seats. The fact is that if the rear seats in the 5 seat Model X do not fold, there would have been no legitimate reason to delay its production. They could have just removed the 3rd row seats and called it a five seater. But they waited because....they wanted to do it right. Right?
It is also a fact that if the rear seats in the 5 seat Model X do not fold flat, I will cancel my order.
