Overall · All generations
★★★★★4.7/5
The 4Runner is expensive to buy used because it lasts. A well-maintained example easily clears 300,000 miles. The main things to inspect are the KDSS suspension (if equipped), the frame, and any lift or heavy off-road history.

The 1GR-FE V6 is nearly maintenance-free beyond fluids, brakes, and tires. Timing chain, not belt.

The 5-speed automatic is old but proven — routine fluid service extends its life meaningfully.

Before you buy

Inspection Checklist

What to verify on any candidate car.

Frame
Serious rust or perforation is a walk-away.
KDSS
If equipped, check for leaks and correct operation.
Suspension
Lower ball joints, upper ball joints, and bushings at 150k+.
Drivetrain
Verify transfer-case and diff fluid service on 4WD examples.
Modifications
Lifted trucks often hide accelerated CV, ball-joint, and driveline wear.
Living with it

Ownership Experience

  • • The 4Runner is trucky, tall, and honest. On-road refinement is behind newer unibody SUVs.
  • • Fuel economy is a genuine trade-off — 17–19 mpg real-world is typical.
  • • Resale value is unmatched in the segment. Parts and knowledgeable mechanics are everywhere.
The Verdict

Should You Buy a Used Toyota 4Runner?
