I agree with Bruce with the fact that many individuals grow up to appreciate one brand over another, and much of that may be due to the way in which you were raised. This brings up the idea of brand loyalty, a customer's favorable attitude toward a specific brand. Customer satisfaction with a brand is a huge requirement in order for that customer to remain "loyal" to your brand.
I believe that many individuals have preferences on what brands they buy. When shopping for shampoo, I rather purchase Biolage over Herbal Essence. Growing up, my family owned three Toyota vehicles, therefore I am now familiar with their products and would potentially want to shop for one myself someday. I do expect certain things from certain brands because if you are continually purchasing their brands, you expect to get positive attributes back from it. With the recent problems with Toyota, it has made me wonder if I should still remain loyal to their company or not. However, after such a positive track record for the past fifteen years with my family, one problem streak should not affect my perception of the last fifteen years of quality service with Toyota.
If you were in my families position with Toyota after owning three vehicles for the past fifteen years, would your perception of their company change after the recent problems they have been going through?
