general problems of the 2003 Lexus GX470

Frame is rotting from inside out, excessive corrosion on an otherwise spotless vehicle. This is a known issue that was common to the early/mid 2000's Toyota tundra, tacoma, and 4runner, the latter of which shares frame components. Toyota, for whatever reason, covered the tundra and tacoma through recalls, but so far has not done a recall on the 4runner or Gx470.
