They are telling me the added cost is for the battery upgrade. I also can't see why the software limit isn't an option. I can't see how the "60" decal for the trunk is such an issue.
I had the PUP, so liftgate was there anyway.
On my X100D, they discontinued the low amp charger, so they added the high amp charger to my X at no added cost. I didn't ask for this upgrade either. I can't see how they aren't just doing the same thing if the battery software limitation is so hard.
They didn't discontinue the 48A charger. What they did was take away the option. The 100's get 72A; everything else gets 48A. I have no idea why Tesla did this. I find having 72/80A charging very useful.
