1. How "exclusive" they are.
2. The age and heritage of the brand
3. How difficult they are to manufacture. (The difficulty could be artificial.)
Jaguar fails on basically all counts. (1) Price isn't necessarily a stand-in for #1 -- on the very high-end, you have to make it actually difficult to acquire the product in question, and they're not going to do that. (2) Jaguar has a reputation that's somewhere from "weird" to "terrible," not the storied reputation of an old French brand like Bugatti. (3) The Chinese can manufacture that car in a heartbeat. Give CATL and BYD free reign, and they'll probably do a much better job of it.
