It's essentially a new car that can't be sold as new due to a technicality, which is that it's been registered. If you had bought one new a few weeks ago, you would have gotten one just like it for the normal selling price, and you'd probably have more miles on it by now anyway. New cars show 100 miles on the paperwork, so it has virtually no use compared to what the original paperwork will show.
You aren't losing much getting it used. You lose out on any promotional interest rates that Lucid might offer. You don't get your choice of colors or options. The difference between a 2023 and 2024 is a character in the VIN.
You won't get, in theory, any free charging at EA, since it doesn't transfer. But you wouldn't get that if you buy a new one unless you had a reservation for one. And people who have bought them used have reported that Lucid didn't remove the free charging after the ownership transfer, so it's possible to have something better than new, if it was sold with free charging for a given time period. But that's not a guarantee.
What it's worth is what it's worth to you. I got a new car, but found a used one before I decided. I made a spreadsheet with all the factors, including difference in finance costs, depreciation (no actual depreciation based on mileage but you'd lose value when you sell it based on model year alone), features (since I could have independently had Lucid change some things after the fact) and ultimately decided that I wanted to go for the exact car I wanted with the exact options in the exact color. For $10k I could have gotten a top quality rap, which I also figured into the calculations. Others might have felt that a different color was not an issue. So it comes down to what matters to you.
