Actually, while true that LC200 is more luxurious, the 200 series is a STRONGER and MORE DURABLE platform than 70 series.
Oh really? I have a hard time picturing 4x power-heated seats, 2 cooled seats, automated power folding mirrors, 4-zone climate control, 4XDVD players in headrest + 1 more in head unit, and things like that breaking when they don't exist. I really don't need those things... and my point is I'd rather have windows that i manually roll down, if it means it will still work in 30 years if i take decent care of the vehicle. The 70s is ideal for me because i don't care about those things, and i'd love a truck that could last me the rest of my life if properly maintained.
I just have a hard time picturing the 200s being more "reliable" past the 2nd decade of its life, because a part of reliability is maintenance cost. Less things to maintain = lower maintenance right? That and, the 70s series is plenty durable enough; but that doesn't matter because we are talking RELIABILITY. If i wanted durability i would buy an Abrams.
Which is it? Neither, because it is true and it is with varying mileage accounted for.
Show me evidence that MOST AHC (rather than a small tiny % of them) owners have to do anything other than an AHC flush, in the same amount of time that MOST of the shocks users have to change out their shocks. Grinchy had some very good points about how numbers on mud may be skewed, because google searches direct people here for AHC-related questions; and even then it's not as many failing AHC threads as you claim.
Anyways, believe what you want but as someone who is driving a 200k+ AHC example myself and have maintenance records to show for it, i can assure you that the cost of maintaining my AHC system is in fact cheaper than the cost of you keeping up with your shocks alone. You providing a few examples and not taking into consideration that even all of the AHC threads you can find added together, the total # of failures still represent a very small fraction of AHC-vehicles out there. Only a handful of AHC owners (less than 1% and im certain you won't find more than that) need to replace anything major before 100k, but how many % of shock users need to replace shocks before 100k?
AHC has been out for decades starting with the 100 series and GXs, and if its as unreliable and high maintenance as you say, then there'd be a mountain of overwhelming evidence against it by now. In reality, it has proven quite reliable and right in line with Toyota's philosophy of thoroughly testing everything before they put it into a Land Cruiser.
With that said, you and i both owe the OP an apology for hijacking his thread. To each their own, and my apologies to OP. Over and out.
