We've updated the results for the Focus to include owner experiences through September 30, 2010. Other sources of car reliability information won't cover the months since April until the summer or even fall of next year.
Repair frequencies, in terms of repair trips per 100 cars per year:
2004: 54, very small sample size
2000: 135, a single car short of the minimum
The 2004 is better than average, all of the others are about average.
Thank you, once again, to everyone who has been helping. We'll have further updates in February and May. With more participants, we could provide more precise information and fully cover all model years.
