Aha! the Ford guru speaks
I also have some concerns about the gas-guzzliness of the Mazda3/Focus AT due to the heavy body and weak engine. Hence I'm a bit inclined towards the MT Focus. Not to mention the MT Focus is cheaper and would probably be 1 km/L more economical on fuel which does add up.
Ford Global City's test unit had an unusually stiff gear shift, for some reason (along with the cheesy non-engraved gear numbers). At first I was thinking it was because the car was relatively new and the shift bushings were still hard. But the FD Civic and even City stick shifts I tried were much, much smoother.
Also, regarding the Ford rattling. How does it compare to Mazda rattling? my old 626 doesn't count (it's a veritable spawning pool of rattles, because it's ancient).
