I don't think anyone is claiming the Lucid will be more expensive to repair than other premium cars. They are ALL very expensive to repair, especially the German brands. It's why I bought extended warranties on all of them if available. I usually did it at time of car purchase even if I didn't plan to keep the car more than four years, as the manufacturer/dealer warranties were discounted with early purchase, were transferable, and raised the resale value of the car if still in warranty. In fact, the only way I was able to sell my problem-plagued 2004 Mercedes SL55 AMG was because it had an extended warranty. The buyer wouldn't take the car until he obtained a written acknowledgment from the warranty company that they would transfer the warranty to him.
This, along with resale value, is another factor in the equation about whether or when to sell or trade a car. While my current thinking is to sell at the 4-year mark, if the resale value at the time is abnormally low (and let's face it, it might be) and the car is still holding up well (which it promises to be), I might decide to keep it and run the risk of expensive repairs.
This Lucid Air is actually the first car I have ever owned that might induce me to take that risk. With every other car I've sold, something more appealing had come to market during the time I owned the car. I track EV developments as closely as I can (having lost all interest in ICE vehicles), and there are not even hints or teases of something coming to market in the next two years that can match the balance of power, handling, range, roominess, and style of the Air.
