I didn't get a chance to read the article. What options does the Sequoia have that the LX doesn't? I agree that the powertrain is a huge benefit over the LX.
On a positive note I have been very pleased to hear the engine and shifting of the LX600 has seen almost universal praise in terms of smoothness, shifts, and acceleration (the reviews in New Mexico at 8,000 feet were consistently beating Lexus claims). Quells any worry of the dreaded 2018 LS experience
Top three off the top of my head are panoramic roof, second row captain's chairs and hybrid powertrain. Neither has front massaging seats, and I wouldn't expect that from a Sequoia but I do from an LX.
Certainly the overall luxury and ambience will be less with the Sequoia, but just my .02, it's far better looking, comes in more models and trims, and you can get it with a hybrid. All of those make it more appealing to me personally. Plus, I'm sure a loaded Sequoia platinum, 1794 or Capstone are going to be $65-87k. That's not too far off LX money.
