What’s my Mercedes-Benz 300SL worth?

Used Mercedes-Benz 300SL at UK specialist dealers are asking from £38,500 to £1,300,000, with a median of £78,995 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.
