Final Thoughts
The Renault Clio is a great small car, but it does have a few weak points, especially when it comes to electronics and gearboxes. Most of these problems are not expensive if caught early, and many can be prevented with regular maintenance.
If you are buying a used Clio, always check the service history and consider getting a pre-purchase inspection. A full vehicle inspection from CAREXAMER starts at just £89 and checks over 300 components, including electrics, suspension, gearbox, and engine health.
