When buying a used car, it is essential to check several aspects. Here are the five key points a mechanic always looks at to avoid unpleasant surprises.
1. Gearbox
An experienced mechanic will carefully examine the gearbox. It will check that each gear shifts smoothly and that there are no strange noises. The clutch is also a crucial point; he will check that it is not slipping and that it is in good condition. A faulty gearbox can lead to costly repairs, so it is essential to ensure it is working properly.
2. Motor
The engine is checked in several ways. The mechanic will start the engine to ensure that it starts smoothly and idles smoothly. By opening the hood, he will check that no part is in poor condition or is emitting suspicious noise. He will also measure cylinder compression to ensure it is adequate, using a specific measuring device.
3. Exhaust system
The exhaust system can reveal a lot about the condition of the engine. If smoke comes from the exhaust pipe when starting, this may indicate a problem. The color of the smoke is also important: white smoke in small amounts may be due to condensation and is not a cause for concern, but gray, blue or black smoke may indicate more serious problems.
4. Oil
The mechanic will check the oil by inspecting the dipstick to measure the quantity and quality of the oil. It will analyze the color, viscosity and odor of the oil, essential elements for diagnosing possible engine problems. Poor quality or insufficient oil can indicate a lack of vehicle maintenance and other potential problems.
5. Brakes
Brakes are a crucial part of vehicle safety. The mechanic will inspect the brake discs and pads, which are wearing parts, to ensure they are in good condition. It will also test braking responsiveness and listen for any unusual noises when applying the brakes, which may indicate problems in the braking system.
Other important points to check
In addition to these five elements, it is also essential to check the vehicle documentation to ensure that there are no administrative charges or issues. It is advisable to request the vehicle's accident and repair history, as well as technical inspection reports (ITV). Verifying actual mileage is also crucial to ensure seller transparency.
By following these tips, you can avoid many problems and make an informed purchase when buying a used car. A thorough examination by a qualified mechanic is always a wise step to ensure that the vehicle is in good condition and ready to serve you for a long time.
