460 vs 470 models, current used prices, worth going newer?

Hey y'all, I've decided this to be the year I save up a little extra money and pull the trigger on one of my dream cars/get ready for the expansion of my family.

I've wanted a 4x4 4Runner for YEARS, I even bought a 3rd gen 2wd a few years ago just to get a taste because I couldn't afford the 4x4 prices at the time.

As those years have passed, I still have an itch for a car that I can do some cross country esque road trips, do a little offroading with and be happy and secure in home maintenance and reliablity. That has come with looking at prices and seeing which cars would be best for me.

I think i've landed on the GX to suit my needs and future needs. We hope to start a family in the coming years, so the safety features and extra space seem great. I know these cars are legendary in their own rites for reliability and offroading, and I think the style fits me more as I've grown older.

So my question, looking at prices TODAY I see the GX470s going for either the same price or maybe 3-5k LESS than the GX460s from 10-14 years ago. The price gap isn't that huge, so I would like to know if it's worth spending a few more bucks to go with a newer model with potentially less miles. I've read about the differences and they don't concern me TOO much, but my main factor here is RELIABILITY and the ability to do MOST of my own maintenance. So please, if you can share some insight on the differences and if you hhave driven both or either, any opinion is welcome. THanks in advance.
