Since the reliability of the car is very worrisome, try to chart the data for each company.

The following data was used as reference.

So, I try to chart the data.

The color of the graph is divided to country-by-country basis.

Bright red: Japan
Green: Italy
Yellow: Germany
White: Czech Republic
Magenta: Spain
Black: South Korea
Bright blue green: France
Blue: United States
Light blue: Sweden
Red: the United Kingdom.

This is a ranking of the failure rate.

This is a ranking by brand of average repair costs.

Porsche is too expensive.

This is the ranking by company of average repair costs multiplied by the failure rate.

German car company low performance is conspicuous.

This ranking is the exponent of by the country.

United States has dropped the car reliablity.

GM and Chrysler would have to be modeled on the Ford.
