I've been in the automotive business for many years....the Edsel was as good as any Mercury at the time, because that's basically what it was.
The car was an ugly duckling with that "horse-collar" front end which failed to excite anyone, even after their largest and most expensive ad campaign up to that point.
Perhaps there is a curse on naming a product after a family member. Steve Job's failed "Lisa" comes to mind. Although the "Oh Henry" candy bar is still around.
