If you're looking to purchase a strong, reliable, luxurious large SUV, the LX 570 is truly the BEST choice available. This is my third Lexus vehicle. I've owned the 2016 LX for a few months, and it is truly confidence inspiring. It feels strong and solid, without sacrificing luxury and comfort. It feels as though it was built to go the ends of the Earth and, more importantly, MAKE IT BACK unscathed!
This is a great vehicle overall, however, the acceleration is abysmal considering the massive engine and the price is foolishly high. This SUV is identical to the Toyota Land Cruiser underneath and even the interior is roughly the same. Lexus added a little more leather and changed the badge. Speaking on the Land Cruiser it handles and drives the same. One of the greatest off-road vehicles you can buy right now, and it will probably outlast you. I do think that there are better options in this class of vehicle if you are not constantly driving off-road. The Range Rover is possibly a bit better off and on road but also has a higher price and checkered reliability. Not a bad vehicle but save yourself $10,000 and get the Land Cruiser.
If you EVER intend to drive in the snow and ice, DRIVE IT on those first. You likely will not buy it. I bought it before the snow flew. In years past, I had driven other LXs on snow and ice and they were great. Thought this one would be even better with improvements over the years. NOT! First, all LX models in the US are shipped with the "optional" 21" wheels/tires. NOBODY makes replacement tires for the size that comes on the car. You are stuck with what comes on it - great in the summer, junk in the winter. Literally the absolute worst tires ever on snow and ice for an SUV. They will not stop this heavy vehicle. When I called/wrote to Lexus to complain about buying a $100k SUV that cannot be safely driven in the snow in Colorado, Lexus was beyond uninterested in the problem. I would not buy this vehicle again, which is unfortunate since in good weather it is very nice. It rides more comfortably than any of the competitors I drove (many) and is much more quiet and refined. The technology is outstanding as is the Mark Levinson stereo (best I have ever heard in any vehicle). The acceleration is very weak though. Definitely not up to par in this class. But it is livable. Gas mileage is abysmal but let's face it, people who buy these cars are probably not terribly concerned with that. Still, it has a relatively small gas tank so I fill it much more than I had to fill my previous Yukon XL Denali (which also got an average of 2-4mpg better than the LX).
