There's no such thing as bad taste

Taste is a social phenomenon. It is a pattern of preferences and choices which is tied to culture, time, place and status. It is therefor relative and never absolute. The term ‘good taste’ could be translated to ‘according to accepted esthetic standards’. No more, no less. There is no such thing as ‘bad’ taste’, though not all tastes are generally accepted.
This is illustrated by the choice of colors of cars. Ford found that people in different cities have different tastes. And I bet the same goes for different countries.
