The seating position in the 80 is more upright, while the 4runner is low like a car, and your legs are closer to horizontal in fron of you. The second gen was way cramped for me (after selling my first 80) and I am short, the third gen I have sat in and was a little better but still "low", the fourth gen was more comfortable but still overall feels like a smaller cabin, though it is fairly close to the 80 series in size.
