Buying a used Citroen C4: what to check before you hand over cash
A checklist for inspecting a used Citroen C4. Engine, gearbox, electrics, paperwork, and what a Honest Car Check report tells you.

TL;DR
Buying a used Citroen C4 requires careful inspection of paperwork, bodywork, and mechanical components. Key checks include verifying the V5C and service history, inspecting for body damage, cold-starting the engine, test driving, and reviewing the MOT history to ensure a sound purchase.
Paperwork
Start with the V5C registration document. Ensure the name matches the seller’s and that the document is genuine. Next, review the service history. A well-maintained Citroen C4 should have a full service history, ideally with stamps from authorised dealers.
Bodywork
Inspect the bodywork for dents, scratches, and rust. Pay special attention to the wheel arches and underbody, as these areas are prone to corrosion. Check the panel gaps for signs of previous accidents or repairs.
Engine Cold-Start
When testing the engine, do a cold start. Listen for any unusual noises, such as knocking or rattling. Check for excessive smoke from the exhaust, which can indicate engine wear. Ensure all warning lights on the dashboard function correctly.
Test Drive Checklist
Take the car for a test drive. Assess the handling and comfort. The steering should feel responsive. Listen for any strange noises from the suspension. Pay attention to the gearbox; it should shift smoothly without hesitation. Check the brakes for effectiveness and any unusual sounds.
Gearbox
If the C4 has an automatic gearbox, ensure it changes gears smoothly. For manual versions, test the clutch for slipping and ensure it engages without difficulty. Look for any fluid leaks under the car, which can indicate gearbox issues.
Electrics
Check all electrical components, including lights, wipers, and the infotainment system. Ensure the air conditioning works effectively. Faulty electrics can be a common issue, so thorough testing is essential.
MOT History
Review the MOT history for the Citroen C4. Look for any recurring failures or advisories, particularly related to emissions or brakes. This history can provide insight into potential future problems.
