I've owned a FJ60, a FZJ80 and now a 4th Gen 4Runner like yours .... the FZJ80 is far and away a closer analogy to your 4Runner then the FJ60 in terms of comfort and a daily driver, no question in my mind. With regard to cargo size, I do believe the FJ60 beats the FZJ80, but it's not by all that much, both have a lot more then your 4Runner. In terms of power and highway driving, the FZJ80 and the 1FZ are FAR more capable then the 2f or 3FE in the 60 series, night and day in my eyes .... no the 1FZ is not "fast" by any measure, but certainly much quicker then the 3FE. I found either engine to be dead reliable and enjoyed working on both .... on the flip side, I found the 5ZE (is that right?) in my 4Runner to be a pain in the *** to work on, especially the friggin starter!! Grrr!
I agree that the 60 series is sexy as hell (although I prefer the round headlights of the FJ60 vs. FJ62) but you mentioned you would be daily driving it and I think the FZJ80 is a much better choice with that in mind. I'm actually thinking about picking up another FJ60 for weekends and whatnot ..... now that I have a 20 mpg V6 4Runner for DD duties
