I found the story in
http://www.lacrossetribune.com/articles/2003/10/18/news/02buick.txt quite interesting: GM finds it has to rename a car, to sell it in Canada.
Here in South America, we have a similar situation, with a strange (for us) car name: "Pajero" is used here as "one who masturbates". In contrast with the Canadian case, the car is actually quite popular here.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
