More on the Citroen C5 Aircross
TL;DR
Before buying a used Citroen C5 Aircross, check the V5C for accuracy, inspect the service history, listen for unusual noises during a cold start, test drive for handling and brakes, and review the MOT history for past issues.
Paperwork
Start with the V5C document. Ensure the Vehicle Identification Number (VIN) matches the one on the car. Check for any discrepancies in ownership details. A full service history is crucial. Look for regular servicing and any major repairs documented.
Bodywork
Inspect the bodywork for signs of rust, dents, or scratches. Pay attention to the condition of the paint and check for mismatched panels, which may indicate previous accidents. Ensure that the doors, bonnet, and boot open and close smoothly.
Engine Cold-Start
When starting the engine, do so from cold. Listen for any unusual noises such as knocking or tapping. Check for excessive smoke from the exhaust. Blue smoke indicates oil burning, while black smoke may suggest fuel issues. Look for fluid leaks under the car.
Test Drive Checklist
During the test drive, assess the steering and handling. The C5 Aircross should feel stable and responsive. Test the brakes for effectiveness and listen for any grinding noises. Check the acceleration and ensure the gearbox shifts smoothly through all gears.
Gearbox
The Citroen C5 Aircross typically comes with either a manual or automatic gearbox. Ensure that the gearbox engages smoothly without any hesitation. If it is an automatic, check for any rough shifts or delays in engagement.
Electrics
Check all electrical components, including lights, wipers, and infotainment systems. Ensure that the air conditioning works effectively. Look for any warning lights on the dashboard during your test drive.
MOT History
Review the MOT history for any past failures or advisories. Common issues may include tyre wear, suspension problems, or emissions failures. This information can provide insight into how well the vehicle has been maintained. Use Honest Car Check to verify mileage and MOT history. This will help you confirm that the car’s history matches the seller’s claims.
