The LX has a different infotainment setup with the stupid Lexus Mouse, the third rows go up and down electronically, the LX will lower once you turn off the car, has a better camera system, has crawl mode and better differential setup for when you are off road.

 

Not sure if the OP is looking anymore, as this thread is 3 months old, but in my opinion the GX and LX are very different vehicles. I found the LX to be much more comfortable, but also that much larger for around town driving. Like you, I've been waiting on the 300 series LX to come out since the 2018 model year, but I'd be surprised it it was even out by 2021 at this point. They just don't sell enough of these trucks to justify a full redesign I guess. I finally gave up on waiting and bought a 2016 yesterday, which I can always trade in when a clean-sheet redesign comes out.

What sold me on the LX was its durability (only vehicle I'm aware of made to last 25 years without major problems in rough conditions), great resale value, and rarity (only 6K units sold per year). GX is a fine truck, but it doesn't feel special in the way the LX does.

 

Thanks for your assistance, I will keep looking as we get closer to the release hopefully we can find a nice 19. Wife said INFINITY this week and I changed the subject.

Thanks
Michael

 

I had both GS luxury with there driver assist package and an LX, after 8 months the GX got traded in for the LX, the gas mileage is very similar, the extra space is appreciated, the LX is over just better. The gx had somewhat jittery ride even with the air suspension, especially for passengers. My vote would go to the LX.
