To get a fair assessment, you should look at:
* Specific year and model: Reliability varies significantly from year to year. Research the specific year's common problems reported by owners.
* Owner reviews: Websites like Edmunds, Consumer Reports, and RepairPal provide owner reviews and reliability ratings that can offer insights into common issues.
* Maintenance history: A well-maintained Focus, regardless of year, will generally be more reliable than one that has been neglected.
In short, you can't make a blanket statement about the entire Ford Focus model line. Some were good, some were less so. Researching the specifics of the car you're considering is crucial.
