Built proof, reliable, near perfect...I bought a '98 SR5 4x4 in 2002 with around 25k on it. I have driven it as my primary vehicle (commuter, highway, hunting and camping) for nearly 14 years. The truck has 155k on it now. I have done regular maintainance and a few minor repairs (small wiring issue at around 70k), nearly no issues.
The motor lacks power, put it serves most purposes other than towing. I love this truck. If you find one with less than 150k, buy it. I can't wait to give it to my daughter and she is only 5. I know it will still be around.
