I suppose for a $36,000 repair to ahc, it would make more sense to just put an aftermarket suspension on it….if the cost is $10,000 or less, though, I’d rather keep the AHC and rebuild it. It’s a very impressive system. Super comfortable and a lift/lowering kit on demand.
As it relates to land rovers…the main difference is the transmission and engine. Sure the air suspension is a constantly maintained thing…but the Land Rover transmission has its own Wikipedia entry for its poor design (lr3’s, lr4’s, l322’s etc). And the engines aren’t that much better.
And the down side to the rovers is even if you replace the engine ($11,000 just for a long block) and transmission (which requires pulling the body off the frame), you’ve still got an engine and transmission that was poorly designed…I like rovers and looked at them quite closely before deciding on a 200.
With a 200 or Toyota product in general, you’re not likely to have engine, transmission, or suspension issues…and if you do…you know you’re replacing it with a part/system designed for 250,000 miles…not one that was poorly designed to begin with (as with the rover).
To reiterate: this is why used land rovers are always so cheap and used Toyota 4x4’s are always so expensive: you’re paying for repairs up front with the Toyota (which are likely never to occur)…and you’re paying for repairs as you go (and get stranded) with a rover.
