Holy cow.
I bought my 85 4Runner new for 18k. At 25k I put a winch, 4" lift, gears, posis, and 33s on it. I drove it for 15 years. At around 140k I did a water pump, headgasket (due to water pump) and oil pump. Brakes replaced a coupla times. Belts and hoses once. Blew a wheel bearing at around 95k, learned to repack them once in a while, and that never happened again. Little things like the rear window switch (too much coffee in it too many times) but nothing ever went wrong with that rig that isn't normal worn out parts in the course of natural aging.

At 240k I sold it to the first guy who looked at it for 10,400.

When you buy used who knows what you get? Can't blame the truck. And now that they are old, they will need maintenance, sure. But the First gens were DEAD reliable - the new ones are not! Toyota lost that edge along the way - their engineering quality went away (start with the 3.0 for an example,) even though I feel their build quality is still excellent.

Plus you can actually fix stuff on a first gen, and if you modify it all the computers don't go haywire and refuse to let you drive it.
