Year over year
What changed
- Ford celebrated Bronco's 25th year with a limited Currant Red Silver Anniversary model.
- Two-sided galvanized steel expanded corrosion protection on the hood and front doors.
- The established EFI engine and E4OD structure continued.
Worth knowing
Notable
- The brochure calls the Silver Anniversary a limited-production model, not merely an aftermarket appearance theme.
- Eddie Bauer used the 5.0-liter V8/five-speed outside Ford's stated California automatic exception.
Living with it
Reliability & ownership notes
- Verify Silver Anniversary identity through original Currant Red finish, emblems, and equipment rather than later-added badges.
- Confirm the exact powertrain, then inspect E4OD operation, rear ABS, hubs, tailgate glass, roof seals, and corrosion.
