DS 5 buying questions

Is a 2015–2018 DS 5 worth buying?

The problem cards above list the model-level checks for this guide. Read them as priorities for inspection and paperwork review, not proof that every example will have those faults.

What should I check before buying a DS 5?

Look for evidence, not just assurances: MOT advisories, service history, repair invoices, warning lights, fluid leaks, tyre and brake condition, and how the car behaves on a proper test drive.
