New Mazda3 can take on Focus and Golf

It seems incongruous in a business where pushing technological and engineering boundaries are a commonplace taken-for-granted thing, that certain cars can maintain their position at the head of the sales charts not so much for years, but for decades, without really being challenged even by a determined opposition.

Except they have not been toppled, despite being challenged by a plethora of other manufacturers over a fantastically long period of time.
