I agree.
They're free to change the price at any time right now too - and pricing is partly based on their own supply-chain.
I wasn't advocating or suggesting that Telsa should be able to change the price after you've signed the order agreement. What I am advocating for is some kind of advance-notice to prevent buyer's remorse and to keep customers happy.
Right now, the process is this:
1. Customer submits Custom Order online, pays the $2500 custom order deposit.
2. Customer waits 1-3 months for the order to be produced.
3. During this waiting period, news breaks of a significant update.4
4. While the customer is waiting, if their car had already entered production such that they miss the new update then they technically have the option of canceling their custom order and forfeiting their $2500 deposit and then make a new custom order (for another $2500 - so that's $5000 spent) with another 1-3 month wait with the update. I accept it's likely that a sympathetic SA/DS might be able to pull some strings to perhaps waive at least one of those $2500 payments, and it's true that we all contractually agreed to forfeit the $2500 if we ever change our minds - I accept that.
Instead, I'm proposing that after step 1: after the customer has paid the deposit, if there is a significant update planned then Tesla might advise the customer of something in-the-works and asking if they're okay with waiting an extra couple of weeks to ensure that their order gets the update - saving the customer the hassle (and another 1-3 month wait), but boosting their happiness with the company - while costing the company the extra custom-order revenue they would have otherwise received.
