Fusion engines have timing chain
Ford Fusion is a decent choice for a used family sedan offers excellent handling and good road feel. I would suggest looking for lower kms maybe in 80,000-100,000 area. Might be worth shopping around for lower mileage and even if the asking price is little higher, make a reasonable offer you might get lucky. Not sure how the used market is in Ontario at this time but it always nice to get a lower mileage car for the same amount you are looking to spend.
That said if you are keen on the one you described above make sure you check the used car history records, check the service records if available to verify that the car was properly maintained. Make sure to test the air conditioner operation & have the car inspected by a mechanic of your choice.Properly maintained this car will be a good choice it is good value for the money.
