How many km's does a Ford Fusion last?
This question is entirely dependent on how you drive. If your friends refer to your driving style as "Miss Daisy" rather than "Lewis Hamilton", and you get your car serviced regularly, then there's no reason a Ford Fusion shouldn't last at least a decade before needing major maintenance work.
However, if you prefer to model your driving style on a mix of New York cabbie or teenage Grand Theft Auto-player, then you'll probably end up visiting your service department quite a lot to fix broken parts.
