I would not be surprised to see the TRD Pro push $60k in a 6th gen, but with inflation and the odds being it's a 24'.....who knows. The 23' Sequoia TRD Pro is reported to start at $66k, and the 2022 was in the $64K range. Should the 4runner follow a similar path it would keep them under $60k. It seems like they'd want to keep a price gap to the Sequoia.
What would I pay for it? Considering it has less tech than a $40k Rav4, not very much, a current 2022 TRD Pro.....~$45k. We're talking about lacking and OLD features, no power, poor MPG, 5sp tranny, no front locker, if the body didn't look so good, and there's literally no competition for it if you want/need a 3rd row SUV that can off-road, no one would buy it. Not when the Jeep/Bronco has more off-road prowess, more power, tons more tech for almost the same pricing. I can appreciate low tech/reliable, but price has to reflect what it's lacking. Jeep/Ford are making much more capable off road packages WITH all the tech for around the $60k (if we set stupid markups aside).
It's why in 20' when I got rid of my 98' S10 I had driven for 19 years I went into a full size pickup over a 4-runner. Better safety rating, HD 360 cameras, heated steering wheel, much better interior, quieter ride, more towing/hauling, 430hp and 460 ft/lbs torque with the same MPG, blind-spot monitoring, heated/ventilated seats, way more rear seat room, the list goes on for what was only about $4k more. Does it off-road as well as a 4-runner...of course not, but it does the off-roading I need to, and does everything else way better.
I simply won't buy one until they either price them according to how far behind the competition they are, or they realize what Ford/GM/Jeep etc. have that people want the tech/features along with the off road performance, especially when it's only a $5k price difference and we're talking $55k+ vehicles. Even when the 6th gen comes out it seems unlikely they will put the same motor in it that the Sequoia has, which means it's probably going to get a turbo 4 hybrid, so if it's not mid-300hp no thanks. If they destroy the rear cargo area with the "hybrid hump" and non-removable seats like they did the 23' sequoia I won't buy one at any price. I bet the 23' Sequoia lost almost 25% of it's cargo space with the new design.
