Yukon XL brochures mention seating for 6, 7, 8 or 9 throughout the years. That pic is for the 6 passenger. Seven and eight passenger gets the more common 3rd row seat made for two or three without the consoles and/or a 2nd row bench seat. Nine passenger was available in the Yukon XL with the armrest in the front bench seat that folded down into a mini seat between the passenger and driver, 2nd row bench seat for 3 and third row seat for three.
If you've got one of he oddballs, post up a picture ... Here's our 08 Denali AWD with seating for 8 after a $7h detail that took a 2 day color sand, interior and exterior detail from a shop that did resto on trade in's for dealers. Buyer drove from out of state and gladly paid $11.5k @ 140k miles last year. It was cleaner and better than we got it in 2014.
