2001 Toyota 4Runner Reviews
I have a 2001 Toyota 4-runner two wheel drive v6? I have aprox 250,000 miles and have had to do NOTHING but change the oil and brakes. What a GREAT vehicle. I have always driven Jeep or Lexus. I know they are related but I hope to never own another Lexus. This car if very plain and a little small ..no creature comforts but is hands down the best vehicle I have ever owned. I am the second owner...
