1991's Worst Car Manufacturers by Number of Manufacturer's 1991 Cars to Avoid Divided by All of Its 1991 Cars Rated in 1997

For this quality measure, we divide the car maker's number of 1991 models on CR's 1997 list of Used Cars to Avoid by the number of its 1991 models rated in Consumer Reports' April 1997 Reliability Tables. This computation is done with the intent to garner a rough estimate as to how likely a brand's models will be among the Cars to Avoid at about 5 ½ years.

The 6 worst 1991 car manufacturers by this quality measure are, in descending order (worst first):

  • Hyundai Motor Company, with a quotient value of 1.00 based on 1 rated model
  • Isuzu Motors Ltd (a General Motors affiliate), with a quotient value of 1.00 based on 1 rated model
  • Ford Motor Company, with a quotient value of 0.54 based on 26 rated models
  • Chrysler Corporation, with a quotient value of 0.52 based on 27 rated models
  • General Motors Corporation, with a quotient value of 0.30 based on 47 rated models
  • Mazda Motor Corporation, with a quotient value of 0.13 based on 8 rated models
All of the car company quotients that are greater than 0 for model year 1991 are depicted in the following bar graph.

This s a bar graph of 1991’s worst car makers by dividing the number of the manufacturer’s 1991 Cars to Avoid in 1997 by all of its 1991 rated cars in Consumer Reports’ April 1997 Reliability Tables. Chart by James Benjamin Bleeker, 20 March 2012.

Worthy of note is that Hyundai Motor Company went from one of the worst (worst by this measure of reliability-durability) in 1991 to one of 2006's 3 best manufacturers.
 
The Prizm, a rebadge of the Corolla, is not included in the above computations.
