In late May and early June 2001, a survey of owners of high mileage Toyota motor vehicles exhibited on internet galleries or listed on internet rosters was conducted. In the questionnaire, there were several queries regarding durability. The queries included:

  5   No

Query No. 10 How the Engine Presently Runs:

  3   It runs now as well as it did when it was new.

  0   One or more barely operate at all.

Query No. 27 Estimation as to when the owner's Toyota vehicle operated or will operate as a typical Big Three vehicle at 3,000 miles, by those who judged themselves as having a basis sufficient to make an estimate:

Query No. 28 Estimation as to when the owner's Toyota vehicle operated or will operate as a typical Big Three vehicle at 6,000 miles, by those who judged themselves as having a basis sufficient to make an estimate:

Query No. 29 Estimation as to when the owner's Toyota vehicle operated or will operate as a typical Big Three vehicle at 22,000 miles, by those who judged themselves as having a basis sufficient to make an estimate:

Caveats: The number of respondents is small. The plots for some models may be dramatically to the right of the plots for other models and the above plots. Notably, the plots for a mid-1980s made in Japan Corolla, the then flagship of Toyota Motor Corporation, may be very markedly to the right of the above plots for queries 27 through 31.

1 Mazda's one entry, the Mazda3 i, may have been pulled from Consumer Reports' Overall Quick Pick List due to a "Poor" side-impact crash test rating by the Insurance Institute for Highway Safety. The Insurance Institute's rating did cause Consumer Reports to pull the Mazda3 from its recommended list.
All shares are rounded to two significant digits.
