Best Model Years
All 3rd generation 4Runners (1996-2002) are highly regarded, but 1999-2002 models often benefit from minor refinements and updated styling.
Years to Avoid
None stand out as inherently bad, but 1996-1998 models may have earlier versions of the 5VZ-FE engine (still excellent, but some minor differences) and are older, so rust and wear are more likely.
Biggest Strengths
- Legendary 3.4L V6 engine (5VZ-FE)
- Robust frame-on-body construction
- Exceptional off-road capability and durability

The mileage windows when the 1999 Toyota 4Runner most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
