Ha ha the dark side huh? It's amazing how quickly that escalated. You make a good case for AHC. I hadn't really thought through all the pros of the system. It seems like most people are of the opinion that it needs to go as soon as possible but for a truck that isn't doing long distances in the backcountry it might make sense to keep it around. I'm going to need to take some time and meditate on this and reevaluate my life.

Ah that seems like a pretty good deal with all the work that's been done and its condition. I'll check it out, thanks for the tip.

As soon as I typed “which leads to fear” I knew where the rest of that sentence was headed. Master Yota.
Click that link and feast your eyes on 20 pages of glorious AHC explanation.
This should be a sticky, quality content like this gets buried!
AHC is an incredible system!!
Repost from just one comment before yours but if anything should be sticky it’s that link. And anything PADDO has written about the system. (IIRC) He has years experience with military hardware and says the AHC is military spec in its robustness.
Where did all the 100's go? They were relatively cheap on the US used market so a few of them got exported to Russia, Africa, and SE Asia.

When I was looking for my 100, there was a few times I found one and when I called to ask if I can go see it, they said it's already purchased and getting picked up to get transported to another country.
^^^^^ This aspect of the system (if working properly) really can not be overstated and I am glad you brought it up.
Last summer while visiting family in Austin I learned just how valuable it could be.
Getting ready to head home after our visit...I had just dropped my Daughter off at the airport and we were on I-35 going about 60 mph.
Conditions: Light rain falling, 6:30 a.m. not quite light yet because of the cloud cover, traffic medium.
Cargo: Myself and my Wife, our two Dachshunds and luggage etc...for a 3 day trip.
Incident: I am traveling in the middle lane of the 3 lane interstate. Basically keeping pace with the traffic, but some vehicles going slower, some faster. As we approached an overpass I could see a vehicle that had stopped (possibly died) half on and half off the inside lane of traffic...!!!!
A White Suburban (in that lane) saw it too (just before they were about to rear end it at 60mph). The driver of that vehicle (slightly ahead of me and in the lane to my right), swerved HARD to miss the parked vehicle. The Suburban is now in MY lane and swapping ends on the rain slick highway.
I got on my brakes as hard as I dared without locking them up and simultaneously made a hard lane change to my left to avoid hitting the Suburban which was quickly slowing down and still doing loops.
I just managed to miss it but then noticed in my rear-view that another vehicle was coming up behind me fast. So...I punched the throttle and pulled the Lexus hard back to the right to get back into my original lane.
The Suburban ended up being hit by two other vehicles.
I can tell you for certain....if not for the AHC reacting and keeping the Lexus 'flat' we might have been spinning down the highway as well. As it was, good tires and the AHC working correctly resulted in me being able to a make two HARD evasive maneuvers with only slight counter steer required on one.
My wife was white as a sheet and could not believe we got out of that situation. It did indeed happen very quickly and because I am adamant about checking my mirrors and knowing where other traffic is...did I know I could get over into the next lane, because we going to plow into the Suburban otherwise.
The LX was not made to run a Slalom Course...but it did that morning.

Toyota came out with the sequoia and tanked the land cruiser sales with a cheaper, bigger SUV with similar features. the cruiser became a niche vehicle after that.

Here's the sequoia sales:
Yeah, I can’t find it now, but one of the first YouTube videos I watched when I got my LX was one doing donuts on a grass field and I was SHOCKED how flat it stayed the whole time. I thought for sure a big top heavy truck would flip over. I did some donuts in it in a field one time (only to confirm it’s stability, of course).
^^^^
Or just horrendous body roll. That's what happened to the Suburban. When the driver jerked the wheel to the left it shot the Sub out into my lane...and when they tried to straighten up (come back to the right) the body roll broke the rear end loose. They were unable to 'catch' it. So next thing I saw was all three brake lights come on, then the Sub start spinning. I saw brake lights, then headlights, brake lights, then headlights again...all the while its slowing down right in front of me. At one point the vehicle wasn't more than 30' in front of my bumper.
I had to jerk the wheel on my LX hard while stabbing the brakes. So normally that would result in the front end diving hard (shifting weight to front, unloading the rear) AND body roll. Well...until the anti-lock brakes take over and basically boost you ahead! I barely got around the Sub with that maneuver and had to counter steer a bit to straighten up in the next lane over.
Then I had to get myself out of the way of a vehicle that was coming up fast behind me by punching the throttle and jerking it back into my original lane. Again, lots of body roll if not for the AHC.
I could see in my rear view mirror the Sub getting hit twice by two different vehicles that couldn't stop or get out of its way, but thankfully it was at much lower speed by then.
It was all kind of 'special'.
Does the older AHC system so all that automatic safety stuff or is that just the models with the ATRAC and all that?
AHC equipped vehicles also feature Anti-Squat and Anti-Dive.
Check this out: https://st.club-lexus.ru/attach/u/6b15e9be.pdf I’d guess you have everything but the ATRAC related stuff
The system is constantly making adjustments with respect to firmness and attempts to keep the vehicle relatively flat and level (within parameters) in all driving conditions.
I don't think the idea was so much 'safety' as it was aimed at providing a smooth and responsive ride. However, the result is indeed increased controllability under some very severe conditions (input).
From the literature cited by 'Das':
"Anti-Roll Control:
During cornering, this function makes the damping force firmer, thus restraining the body roll speed in order to provide excellent stability and controllability.
Anti-Dive Control:
During braking, this function makes damping force firmer to restrain body dive, thus ensuring excellent stability and controllability.
Anti-Squat Control:
During acceleration, this function makes damping force firmer to minimize changes in the body posture to provide excellent stability and controllability."
^^^^^^ Just some of what the system does.
Note: After my incident I was immediately aware of just how flat and responsive the vehicle remained during some hard/fast maneuvering. Very impressive considering the vehicle type.
