is that what the online config says? If so then the answer is yes. Third row seating is a sales item and not a truly useful item in the real world. Folks buying AB level rigs are not hauling kids to soccer or cruising the mall. Try them out at your your local dealer and you will see that buying a full AB is not what a glorified 7 seater Sport is for. The LR4 has far more third seat room for family adventures than the 494. Your money may be be better spent on a different LR product that better matches your actual needs instead of image.
I configured a full loaded supercharged dynamic with a AB. I added all the extras that the AB offered. The difference was about $10k. The only difference is the difference in leather material. Is that basically it?
