What’s my Ford Sierra worth?
Used Ford Sierra at UK specialist dealers are asking from £34,995 to £199,995, with a median of £64,995 today (10 for sale).
These are asking prices, not what cars sell for or what a dealer would pay you. Buyers usually negotiate, and a dealer buying your car offers less than it would ask, to cover preparation, a warranty and its margin.
