The MERCEDES-BENZ C CLASS SALOON (2018-21) C300 4DR SALOON 2.0 258 GPF SS EU6 AMG LINE EDITION PREMIUM PLUS 9G-T+ AUTO is a polished, roomy executive saloon, sitting above mainstream family cars and competing with the BMW 3 Series and Audi A4. Its four doors and useful boot make it practical without the bulk of an SUV. Mycarcheck.com checks are limited: five look-ups covered two distinct VINs, so the figures are a small snapshot rather than a broad reliability verdict. They show an average private-sale value of £25,900, recent mileage of 58,000 miles and annual use of 10,000 miles. Recorded owners averaged 1.4, suggesting relatively few changes of keeper in this sample. The C300 suits commuters and families seeking comfort, styling and confident motorway performance. Premium Plus equipment adds luxury, while AMG Line trim looks sportier. It balances refinement and pace against rivals; check history, condition and running costs before buying.
