Used Mercedes C‑Class Coupé and Cabriolet (Mk4, 2015–2023) buyer’s guide

# Overview

# What changed through the life cycle The Coupé arrived in December 2015 and the Cabriolet in September 2016. In July 2018 Mercedes applied a facelift across both lines. Facelift highlights include a 10.25‑inch infotainment screen, digital instrument cluster, upgraded nine‑speaker hi‑fi, sports suspension standard and refreshed exterior styling. Engine options included C200 and C300 petrols, C220d and C250d diesels, plus C43 and C63 AMG performance variants. A C63 S and other AMG outputs were part of the range.

# Key issues to check before you buy

• Use the car's VIN at tinyurl.com/yc562a2t to check outstanding recalls and make sure any recall work has been completed. The guide flags multiple recalls as a reason for caution.
• Inspect service history and confirm routine maintenance, especially on higher‑powered models and diesels.

• Consider ownership costs for AMGs: higher fuel use, heavier servicing bills and more expensive consumables.

# Alternatives Direct alternatives include the Audi A5 and BMW 4 Series, both available in coupé and open forms across similar model years. The guide suggests both when buyers want comparable tech, engines and everyday usability.

# Verdict These Mk4 C‑Class two‑door cars remain desirable if you focus searches carefully and confirm recall work and service history. Choose trim and engine to match your budget for running costs versus performance, and prioritise a facelift example if you value the larger screen and digital instruments.
