Why are Ford Foci known for their reliability?

I have been considering purchasing a Ford Focus, but I have heard mixed opinions about their reliability. Can anyone offer insight on the overall reliability of Ford Foci and any common issues to look out for?

In my experience, Ford Foci are some of the most reliable cars on the market. I have owned one for 5 years without any major issues.

I have heard mixed opinions as well, but my friend has a Ford Focus that has been running smoothly for over 10 years now.
