About this car

This 2018 Mercedes-Benz C Class AMG Line is advertised with 24,300 miles, approximately 40,400 below the typical mileage for its age. Its asking price of £18,000 is £654 below our estimate of £18,654. The estimate uses 4,483 UK dealer adverts for the Mercedes-Benz C Class, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 101 days ago. Its asking price has since fallen by £1,273. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 11 December 2026, and the latest recorded mileage is consistent with the advert. The seller is Exclusive Motor Company, based in Harlow.

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 4,483 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 40,400 miles lower than typical for a 2018 Mercedes-Benz C Class.

The advertised mileage is consistent with the last MOT reading.
