Interesting dilemma, certainly a first world problem
I must say am very happy with my 2021 LC200 and do not plan to sell it for the next 25 years. Just slowly build on it, knowing I can enjoy it for a long time.
What I like in specific of the 200 series:
- the more traditional Japanese Toyota looks compared to the latest Toyota creations
- the 2016+ head light styling leaning towards the awesome 80 series
- the 2016+ hood shape (i know, this is minor)
- the great V8 and the 8 speed which I leave in ECT mode and shifts with no issues
- the fact it was over designed by a big group of mostly Japanese engineers in Japan in the late nineties/early two thousands. Do not think any Hillbilly Engineer got involved in the 200 looking to add a bigger screen or car play or some fancy gear shifter or extravagant looks. Clearly the focus of the 200 series was to build a worthy 80 and 100 series successor to be the durable and capable ultimate King of all roads.
IMO Toyota with recent designs (Sequoia, Tundra, RAV4, Tacoma, GX550, LC Prado 250) is focused on styling, features and marketing. Nobody can blame them, but not clear yet they are build to last as long as before, time will tell of course. I recall Mercedes basically losing it in the late nineties and still are lost from otherwise awesome vehicle such as the W124 in the early nineties.
If they only build them this way in 2024, I would consider saving for one.
Clearly with a later model year you will be happy to know it can last another 300k miles+ or 15 to 20 years+
Regarding the GX550, it looks to me it is offering the Jeep/Bronco type "screaming" looks instead of being a more simple, understated and timeless design like the 100 and 200 series. It is also based on the lighter duty Prado line. Nothing wrong with that but for the same price you can buy the 200 series which probably will outlast the GX550. If however you really fancy the GX550 (all our tastes and likes differ, it is good we are all different), I would keep the 2013 LC200 and test drive a 3rd or 4th model year GX550, once they worked out the issues and dealers treat you normal again.
Good luck with the choice!
