Added comments for clarity to Teckis300 long list, as many aspects the 16 or 18+ LC200 also has and really few things which actually make a difference with some in fact in favor of the LC200 16 or 18+ (87 octane, better 360 camera projection, less complexity on details like electric vs manual rear seat movement, sunshade, cornering headlights, poorly done heads up display etc).
Now if you want to mount bigger than 33inch wheels AHC has advantages from a clearance point of view and if that is important to you, I would carefully study this forum. Also means you need to get aftermarket bumpers for sure on the LX570 low chin.
Also when towing the AHC will keep the vehicle level though I prefer the LC200 coil spring setup with Firestone airbags or better Australian made Airbagman airbags, which easily ship international to the US. More robust and simple for combined high tow hook and occupants/cargo loading.
All in all though both great vehicles. All the best making up your mind!
1) Substantially more sound deadening (16+ LC has a lot of this and is very quiet inside, I know from direct comparison driving a 2021 LC200 and a 2020 LX570)
2) Powered rear hatch for open/close (later LCs got this - correct 18+)
3) Soft open rear lower tailgate, with power latching (18+ LC 200 also, do not find it important though)
4) Surround camera system (16+ LC200 has this with larger in obstructed screen view. Comes on at low speed. Very useful feature)
5) Ventilated/Heated front row (later LCs got this - correct from 14+ I understand)
6) Mark Levinson Reference w/ 5.1 surround (LC sound system perfectly fine, key is both vehicle are quiet inside which makes listening to music easy. I do not want concert type volume so difference a mute point)
7) Power side view mirrors with auto-fold (later LCs got this - correct, 18+ has this)
8) AHC - AVS, lift on demand, auto and multi-step damping, anti-dive/roll/squat, leveling, etc., etc. (LC200 has KDSS which is excellent and is less complex as long as the KDSS valve body valves are not heavily rusted. I have coated those with a liquid film type fluid and put marine grease in addition. Rusted AHC components can also be an issue)
9) AHC underbody armor (KDSS components also have protection around them, mute point)
10) Shorter roof rack (LC has a longer roof rack with 3 supports per side)
10.5) LC200 allows for easy aftermarket rack install whereas LX570 16+ requires drop off headliner, a major job
11) Steering headlights (AFS) (LC200 headlights are slightly better in my experience and also have auto high beam feature for dark secondary road driving)
12) Projector headlights ('16+ LCs got this)
13) Headlight washers (16+ have this as well)
14) Storage in rear seat armrest (LC200 also has small storage as well, both not very helpful, however LX570 has rear AC controls in there which is totally useless when you have 3 people in the back)
15) Power slide rear seats (Manual on the LC200 set in rear position 99.9% of the time. Will never fail on a LC)
16) Second row storage on front seatbacks is a panel vs net (I do not keep stuff in there and remove when passengers leave anything there as easy to see)
17) 14-way adjustable driver seat vs 10-way LC (passenger 12-way vs 8-way) (As noted, the LX570 front seats are nicer and driver seat area can be adjusted which is the only item I wish my LC200 has. Still I like everything else more on the LC200 so it is what it is)
18) Dual adjustable sliding armrests (to low to be useful in either case and if you like to lean to the right the LC200 armrest is perfectly fine)
19) Power stowage for 3rd row seat (Removed my 3rd row and manual folding is easy and less complex. These are not full seats so get a Sequoia if that is really important)
20) All windows down by holding remote door open button for 3+ seconds (typical Lexus feature, not sure Toyota's have this?) (Yes, all 16+ have this, certainly 18+)
21) All windows down and up by using key fob in door (also not sure LCs have this?) (Same as point 20, LC has this as well, not really a feature which get used a lot. In case of parking in the Sun I keep my driver door open longer as I start the vehicle and then the AC quicks in which is very good)
22) Substantial Lexus key fob (LC uses same one as corolla) (Not true, LC200 18+ has a big and better looking FOB than the LX570 but who really cares)
23) Fade-To-Off interior lighting (I believe LC got this in 2014?)
24) Puddle and side step lights
25) Door sil lighting (16+ LC200 has this)
26) Interior ambient lighting (16+ LC200 and even 14+ I believe have this as well)
27) Additional trunk side light and open tailgate lighting (16+ has this as well unless there is one more aft in the LX570. Will check this on my son in laws 2020 LX570 next time)
28) +2hp / +2tq (requires 91 octane, LC is 87 octane) (This is major BS from Lexus and fuel cost is therefore 20% or so higher, a real reason to get a LC or just use 87 in the 570 as the engine and motor management are identical part numbers and have maps for both)
29) More luxurious interior appointments (Both the 08 to 15 and 16 to 21 LX use a wood color I really do not like and are very old fashioned, excretion is the red interior 16+ or the 2020 amd 2021 “Sport” models with a near black looking wood which passes my grade. Talking taste here so go and drive and make up your own mind. This though is actually a key reason for me together with the exterior to get a LC)
30) Ventilated outboard rear seats
31) Four-zone climate concierge (Controls the seat heating and ventilation, the 16+ LC200 has this for the front where it matters)
32) LED Headlamp with AHS Sequential Turn (16+ LC200 is LED as well amd produces slightly more light than the LX570, though both very good)
33) LED Cornering Lamp (Another feature which can break, I have on my 2014 BMW 535d and is effectively a gimmick unless you live in the countryside on a winding road, which in Europe and Japan exists and hardly does with the straight roads in the US)
34) 12.3-inch high-res split-screen display (LC 9") (LC screen is a better format and shows more of the rear view in reverse than the LX570 screen, in fact we thought the LX570 was defective in comparisons but it is not)
35) Head-up display ( Very poorly done in comparison with other vehicle who have this and just adds complexity and windshield replacement cost)
36) All-Speed Dynamic Radar Cruise Control (LC DRCC for 25mph and up) (This I never use in traffic as it works poorly, but for sure try it amd see what you think)
37) Steering wheel paddle shifter (Only useful in mountains when descending, though how often does that happen)
38) Door puddle projector lamps (already mentioned above)
39) Rear door retractable sun shades (This is an annoyance when going for tinted windows and also as a driver when looking to the left rear)
40) 2020 gets special trims: "LX570 Sport" to "LC Heritage" (Worth considering for the more modern looking wood trim, otherwise it adds bumper lips you rather do without)
41) Rear seat entertainment, single screen in early gens, dual in later (Outdated with iPads weapon of choice. Get an LC without it and if you like add iPad supports to the driver and passenger seats instead)
