The Rolls headliner has 1340 fiber lights. You can customize the pattern if you like..... It is threaded by hand and takes over 17 hours to do. FYI. Absolutely worth 12,995 if you want it in a $400k car when all is said and done.
For my money there are many other things the Rolls has which I would choose to put on the Tesla before the headliner. Actually from an interior perspective I would like to have almost everything from the Rolls EXCEPT the lighted headliner.
But to each his own.
And no I don't own the Rolls - although I have ridden in several many times. And I would rather have an S, an X and a 3 than one Rolls.
