About this car

Price and mileage comparison

Estimated market asking price: £7,059. The asking price is £769 below this estimate.

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 365 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 12,500 miles higher than typical for a 2004 Mercedes-Benz SL.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
