I did this with an XC40 Recharge back in November, 2021 (when my MX EDD was April - that was exactly 5 months). I am loving the car. Volvo delivered it to my local dealer within 2 weeks and I have been driving it ever since. The Care by Volvo program is perfect for our situation here as it goes month-month after 5 months for up to 24 months - the way Tesla is going it may be the latter
. So you can just keep driving it without worry and whenever your X finally arrives, you return the car.
But yeah, no complaints with Volvo at all.
