Model X owners are in more of a bind. The different seating arrangements are not available in the Plaid.
This has actually hurt X Plaid sales because several people including myself ended up with LR just so we could have the more usable seating setup of 5/7 seater. As I’ve said a bunch of times I need the seats to fold flat. Not possible in 6 seater.
Tesla would have gotten $20k more out of me if Plaid came with 5/7 seater. Now they can get $10k out of me if they offer boost for X LR.
Guess they don’t want my money.
While I do think there is merit to what you're saying, Tesla confirmed with me that the reason why is 6 seat is most popular config and it also streamlines production by not having the others as options on a Plaid (workers know exactly what to build). As to how many people would actually upgrade to a Plaid with other seat options versus how much money Tesla's actually saving by only offering one is anyone's guess.
