I should add that having now uploaded the photos, the process of converting them to JPEG and then uploading to this site seems to have resulted in exaggerating the iridescence a bit
In real life the car is stunning, to be sure, but a little bit more subdued that these photos make it seem.
What's interesting is when the sun goes behind a cloud, much of the iridescent effect goes away, and the car looks more like a shiny silver Model 3. The owner told us that at night, the car really gets attention, especially at a red light or surrounded by other colored lights while driving. It also apparently appears "invisible" at night at times.
