The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.
The pricing calculation includes 368 adverts of this make and model across different ages and specifications.
Advertised mileage is approximately 34,700 miles higher than typical for a 2003 Mercedes-Benz SL.
Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
