the lr3 is simply the best overall value though, period. none of the engine BS to deal with and massively cheaper. I have bought many new cars, some up to $100k, most more than what a new lr4 was, so i can appreciate the desire for newer, faster, etc. but now I've completely switched to how cheap can i accomplish my needs with a vehicle. Not meaning "cheap" as in low quality, as i still buy the bigger pressure washer or better tools and best tire possible, but in this scenario, you could find a soccer mommer lr3 for 1/4-1/3 the cost of an lr4 and use the remainder to really build it out with no compromises or an offroad trailer, etc.
I see so many people blowing their *** on an lr4, low miles, etc then they try justifying tires that are "good enough" instead of the best or won't spend the $ to get the spare tire onto the bumper. It's mind boggling.
At this point, a 2-4 yr old lr4 will depreciate in a couple yrs more than my lr3 is worth. That extra $ spent is worth what exactly...? zero aside from just enjoying newer shinier things.
Same thought process goes for GX LX LC etc. The value spot now in land cruisers is the 100 series. $12-$18k gets you a 2006+ Land Cruiser 100 series w heated seats, decent enough touch nav, probably ACH leveling, no fuss solid platform. However the 200 series first few years are now into a value range too and a true step up from the 100 series in trim, systems, design.
It's interesting to compare that the differences from lr3 to lr4 are really not that much aside from the sweet engine. LC 200 got not only a much more powerful engine but also ventilated seats and totally re-engineered chassis especially the funky front end where the 100 series had the torsion bars. 200 got all new KDSS which disconnects the sway bars off road for really nice front end articulation. The rear is still a solid axle which is better for towing.
There are pros and cons for sure. I actually like the unique chassis/body engineering of our lr3/4 being a unibody on a ladder frame. I don't know of any other suv made who did that. It's why ours is so solid in that aspect.
