That price is about right for a 2013 with that mileage, depending on condition and service history. Make sure to get the CarFax and have a pre-purchase inspection done. That’s non-negotiable when buying used.
The Fusion competes well with the Altima and Accord in terms of value, but honestly the Accord ages better. More people want them, so resale is better. If you’re planning to keep it long-term though, Fusion is fine.
The used market is weird right now. Fusions are definitely a better buy than they were five years ago because prices dropped significantly. New car prices pushed people toward quality used vehicles.
