The MERCEDES-BENZ C CLASS SALOON (2018-21) C300DE 4DR SALOON 2.0D PIH 13.5KWH 306 DPFR SS EU6 AMG LINE NIGHT EDITION PREMIUM 9G-T+ AUTO is a premium plug-in hybrid saloon in the UK's executive-car class, combining diesel power with electric driving for a more efficient alternative to conventional rivals. Mycarcheck.com recorded 48 checks covering 31 distinct vehicles, a useful snapshot rather than a full reliability survey. Those checks show an average recorded mileage of 43,000 and annual use of 7,000 miles; the average private-sale valuation was £34,600. The low 0.5 average previous keepers suggests many checked examples had limited ownership changes. Comfortable, equipped and easy to drive, the C300de suits commuters and families who can charge for shorter electric trips, while diesel range helps on longer journeys. Its premium feel and fuel savings distinguish it from petrol-only saloons, though economy depends on charging habits. Check a used car’s history and condition first.
