I've owned a bunch of Jeeps, still own one. The 80 series is incredible in my opinion. Fit and finish is industrial, yet refined. What I mean is, everything is built tough, but it doesn't leave you with that big truck/ minimalist feeling.
Compared to my 4.0 HO XJ, the FJ is slower, BUT. Really after driving the slower of the 80 series (3FE), I've gotten used to her. AND really she moves along just fine. They still have some power, but the ride, and build is really incredible. I drive mine every day with 210,000 miles on the clock, and would drive it anywhere. Reliable, worry free driving. I've been pulling a trailer, wheelin' in some of the most ridiculous mud on a j home building job site, pulled a whole palette of 105 8" concrete block about 50 feet, piled her insides with tons of construction gear, and just a lot of general abuse. Cold weather, warm weather, just anything you throw at these things, they will gladly take it.
I really thought I's d swap out to a 350 Chebby, but these 80's are all about the Yota thing. They aren't meant to move fast, they're meant to move mountains. I'll rebuild the 3FE when, if she ever goes. I've become a really big fan of the timing gear driven 3FE, and non-computerized tranny. The whole thing just screams utility... now if only I could convince my local rental center that I can pul a trailer with a bobcat on it...
Hopping from the XJ to the 80, I really notice how tight the Yota is, even with over 200 grand on the clock.
The 80 series really is a Classic 4x4 Yota. There just isn't anything like them on the planet.
Find one that has been well cared for. I found one with a lot of maint. and new parts. Well worth the extra cash for a good one.
