It's all subjective. I'm a fairly large guy, and I find it comfortable.
I was offered a newer '24 TRD ORP 4Runner, for 5k OTD with the trade of ours. That's puts it's value at nearly it's original MSRP... That's not bad. Granted it's in perfect condition, and low miles.
Fuel economy is pretty much on par for any gas mid-to-full size BOF truck or SUV I know of. So not like some hybrid unibody much lighter CUV, for sure.
I look at it this way, it gets comparable MPG to any 4Runner ever made. Including the much smaller, lighter, and less powerful 1st, 2nd, and 3rd gen 4Runners. Or the comparably sized 4th gen.
It's certainly not for everyone. But everyone I know who owns one, knows exactly what it is, and loves it.
What the 6th gen will be like, remains to be seen.
