I had a 2012 Ultimate that I just traded after 6 month ownership. Nothing wrong with the car and I loved the rear Presidential seat! However overall I was very disappointed in the car. There is a reason it is $35k less than a BMW 7 series which was my former car. First I felt the car was a bit unsure of itself after 75 mph. Too sloppy and too much wander for me. Second, the audio system while at first glance seems very state of the art, it is not. I have not owned any other car since 2000 that did not have multiple source capability. When my daughter wanted to watch a movie in the back seat, we all had to listen to the movie sound! No headphone option, no multiple source option. This sucks. Also my iPod interface would just randomly freeze up. The solution was turning off the car and restarting. Also no auto dim on the high beams. Even my Jeep had that feature. The Sport mode was indistinguishable from the normal mode for driving. On my Mercedes E 550 Convert., going to Sport makes a huge change in shifting, and performance. Same with BMW. The interior materials were marginal for a $66k car. And even though I liked the Presidential seat, at 6'1" I could not put my legs up. Only a 5' Korean could really use it as intended. So I am going back to a 7 series and very happy.
