Notice at 4:10 salon slider tilted to port an inch. This common in the 100 of 450 completed model 450s that have broken, warped bulkheads that make the floors sag along the center line by up to 1 1/2 inches. Not for sure but not a good sign. The doors adjust but beyond a point adjustment runs out. The broker was sure to have been aware of this design flaw effecting 1/4 of the fleet and so it may have been checked out and is OK
