I have been in possession of this car since its had 150 thousand miles and i've had no major issues with it. Basic maintence and repairs that come with the mileage that I have been able to do myself have kept me happy.
Have put 120,000 miles on the '99 4Runner. The only repair issues are a small oil leak, replacing the clutch every 8-10 years, and a brake job or two. All relatively minor repairs. Handles and drives great. Wonderful in the Colorado snow. Great visibility. Sturdy design. Relatively quiet inside although newer models are even quieter. It's a V6 so it has decent power but not great, especially up mountains.
If you're thinking of buying a used 99 4Runner and it's got 200k miles on it - Do it! Plan to drive mine another 100k miles at least. Older, reliable vehicles are better for your bank account than losing thousands of dollars in depreciation every year. Repair costs have been minimal in the 9 years I've owned it.
This, in my opinion is one of the greatest all-purpose vehicles ever created. It is an absolutely fantastic, drama-free truck that rolls easily down the road, and is capable of crushing the deep mountain snows that fall in our area. I've got over 145k miles on mine, and she asks only for new brakes every couple of years, and a new battery every 4 or 5 years. The build quality is incredible. 16 years old and not one rip in the leather interior. Fuel mileage is kind of poor (avereage about 17 mpg), but incredibly low cost maintenance makes up for that and more.
Ground clearance, multiple drive options - RWD, full-time 4wd, 4wd high and 4wd low. Locking differential. Very easy to drive, and very easy to park (nimble, and not too big). Power window on rear hatch (dog loves this).
They're long past this generation of 4runner. Newer versions have better uphill acceleration, although this one's is just fine.
Bought it used in 2007 with 130000 miles at a used car lot. Now has 18xxxx miles. Still runs strong. As long as you do the regular maintenance. This 4runner will run forever. The cloth interior is still great as I put a cushion on driver seat, a dash cover keeps the dash from cracking. The blue paint still shines as it is always garaged. Only used 4WD once in a muddy situation.
The only drawback is the engine is kind of weak in this day and age IMO.
Reliability, the truck still looks nice even now, capable off-roader, cloth seats is way better than leather.
The 1999 Toyota 4Runner SR5 4x4 (with automatic transmission) is simply the best stock SUV I have seen for off-road use. It is so light that it tends to skim across the surface of mud with the 4x4 engaged, rather than sinking like a Tahoe. It is narrow, so it can make it through skinny trails. It has high ground clearance and skid plates on key components, so it less likely to get damaged. It has a relatively short wheel base (which combined with the high ground clearance and removing the running boards) means it is unlikely to get high centered anywhere, unlike a Suburban. Any it is still very reliable after 115,000 miles.
-Reliability, simplicity and toughness at its best.
-Go anywhere vehicle.
-Low ceiling if purchased with sun roof.
Had to look hard for a 4x4 without a sunroof.
