I received an email from them recently.
As of 10/19, they quoted price of X6 kit of $950 USD, prepayment, with a 6 week lead.
No mention of the X5 kit.
are you going to place an order ?
btw still no response from them...
I don't think so. That's a big ask, to prepay for a 6 week lead. A lot can/could happen in that time.
