The range upgrade price on Model X is still $4500 in the US. I think the price difference between Model S @ $2000 and Model X @ $4500 is ridiculous. I think it is baked in some historical pricing differences of the models - but those have changed many times now and it no longer makes any sense.
I have done the following and would like to ask ALL of you to help me --> Login to MyTesla and use the "escalate a concern to executive management" option and ask them to explain the difference in the pricing of this upgrade. I believe the more of us point out the inconsistency the more pressure Tesla will feel to respond to this issue and do the right thing. Especially now that scammers are trying to take advantage of this price difference.
Thanks for making our voice heard on this issue community.
