From what I’ve heard, what was posted above from 2021 is close to standard for the 650. Maybe a touch higher on the East and West Coast.

ETA: Checked on my source. Bay Area G650 is $350k living locally. Probably the same for the 600. (Contractors are getting $3500/day on the 600.) 650 in LA is around $280-300k. Maybe a touch higher. Good luck.
