why didn't the Dart Herald do well?
Do you want the full 1,000 reasons? Thread drift apart, it's an old and well-worn story. Let's just say botched design, too heavy, dreadful performance, not even Keegan could turn it into a commercial possibility. And of course the fact that the F27 was better on every single important parameter.
And now back to the 748. I need a drink to recover from being reminded about the Herald.
