Model or exterior color options refresh?

[nigelboid]

Does anyone know if Tesla refreshes models at any regular interval or on a specific schedule? I am especially interested in potential new exterior color options.

TIA!

Updates sometimes come a bit after the quarter end (April, July, October). You can also look at the updates over time here:

It's always hard to know if now's the time or if it makes sense to wait. Waiting is safe but you can wait forever.
