Before any viewing, check the specific car's MOT history at our free MOT lookup tool and look for repeated advisories on these systems. If the same advisory appears two cycles in a row without being fixed, the underlying problem is still there.
Which engine is best on the used Mercedes-Benz C-Class?
For most UK buyers, the C220d AMG Line facelift is the pick. It offers the best balance of running cost, performance and resale value across the range, and avoids the specific failure modes common to the other engines.

How to buy a used Mercedes-Benz C-Class — the inspection checklist
The same three steps work for every used car purchase but they matter more on a Mercedes-Benz C-Class because the specific faults above can be expensive if missed:
- Run the reg through the free DVLA reg check — confirms make, model, colour, MOT and tax status. If anything doesn't match the listing, walk away before you go to view.
- Pull the full MOT history — look for repeated advisories on the systems flagged in the common faults above. A car that's had four MOTs all flagging the same wear point hasn't had that wear point fixed.
- Use our pre-purchase inspection guide on the day — covers the bodywork, electrical, mechanical and paperwork checks that catch most problems.
