Condition will depend on how it was maintained and how it was driven. Infrequent oil changes, flooring it when cold, and short city trips, especially in cold weather contribute to shorter engine life. While 145K is "kind of" up there, if it's been properly maintained and treated decent, there' no reason why it won't go 250K+. And finally, remember that 200K miles is the new 100K miles.
*Why don't you take the VIN to a Ford service department and have them run it through OASIS and see what dealer service history it has. It's a freebie.
