After 170,000 miles of 4WD mountain trails (hard core kayaker and climber), highway trips, towing, hauling, being lent to friends, pulling stuff heavier than rated capability, etc., this truck runs like it did when I bought it new 12 years ago. It's been a second vehicle for years now, and I often meet guys who have 400,000+ miles on these trucks. I've never had an iota of trouble with this truck (except for ripping the antenna off in a car wash). This is a truck that will go 500,000 miles, easy. Plus, it's still quick and fast (110 mph). Still looks relatively good. Wouldn't ever sell it. If you were lucky enough to buy one of these, don't ever sell it.
Engine is unbelievably good with more horsepower than needed. Toyo engineers designed this engine for the much heavier 4Runner, so in the Tacoma, it's unbelievable. This Tacoma is one of the best trucks ever built. (I also have an awesome F150).
