I'm the one with the niece Good question. Not sure why not the Tesla, especially since just 2 yrs ago I took her and husband for a drive in a Model 3 and they both said they had to have one. It could be they're just now in the market and doing broad research. Maybe "Cadillac" is something society taught was the best to impress.It doesn't appear that GM is very anxious to keep supporting older EV's or hybrids from what I just heard. A guy in a Volt was right ahead of me, and we both were headed to Harbor Freight. He asked me how I liked my Model Y, and then told me how he is having so much trouble finding parts for his Volt. He said he almost went to Canada for an EGR valve. I have the same concerns about people buying Lucids. What does your niece have against Tesla? At least there are hundreds of thousands of them on the road and you can be assured that Tesla will be around to support them.
They also thought the Lyriq was much less expensive than the Model Y (which I corrected immediately). They are not technical, daring circus artists actually. So show is important, but price means more. Maybe that's all I needed to say. (A Tesla Ad on the latest pricing may have helped here except Tesla prices constantly change which could get expensive to maintain price awareness.)
