Hello, my hubby and I are considering purchasing a Model X. We ordered a Model Y Performance a month ago but EDD keeps getting delayed all the way to April - May now, so we went to the dealer and tried out a Model X. The SA has a MX that's available in inventory to purchase right now but she said that one doesn't have the parking sensors but also doesn't have the new HW4 (built on February 1, 2023). The ones in inventory that still has the parking sensors seem to be the demo ones. Do you think I should get it if it's not HW4 and no parking sensors? Anything else I should know about the MX before purchasing it, or do you recommend me to continue waiting for the MYP? Thank you in advance!
