Low miles is good.
However, that generation has some issues. The door locks/latches can fall apart.
Window lifts, possibly fail.
Ford, and other makers have discontinued most of their dual clutch automatics due to problems, engine stalling caused by them, etc.
With the current generation Fusion, the door locks have no pull up buttons, are all electric. only a red led light on top of the door.
As it is being discontinued for now, I expect they will be sought after cars.
Even the pre 2013's aren't bad cars. Mechanically reliable.
A neighbor has a 2010 since new and doesn't hate it.
If or when Ford brings back a mid size sedan, it will likely be the Chinese version of the Taurus, which is essentially a tweaked Fusion, built on the same CD4 platform. The larger CD5 Taurus is history. I may have the nomenclature confused. It may be CD3, and CD4.
As most of us support family in their occupation's when it is practical, we will lease Fords as long as family is employed by Ford.
No car, company, or person is perfect. If we ever incur a service or quality issue, internal corporate people will be on it. Our family lineage is long with Ford. A departed uncle was a quality control person, and used to tell off his bosses all the time when they were producing junk.
Having many choices in the market is good. Choices are freedoms by all means and ways. It also provides competition which can be incentive to produce a better product. So buy or lease what you like. You can always change, at least in the non personifiction area's. Wait, nope, it's also possible today to change that. Do what ever works best for the individual.
If you get a lemon, and or poor service satisfaction, I think that should be grounds for eliminating the lease disposal fee if toy decide not to lease another product from that manufacturer. It may already be part of the lemon law.
Buy what you prefer.
