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

TL;DR
The Lexus NX is a reliable SUV known for its solid performance and safety features. Key checks before purchasing include verifying the V5C registration, inspecting bodywork for damage, assessing engine performance, and reviewing the MOT history. Pay attention to the infotainment system, particularly in older models.
Paperwork
Start with the V5C registration document. Ensure the details match the seller and the vehicle. A full service history is crucial, showing regular maintenance and any repairs. Look for stamps from authorised dealers, especially for hybrid models. It is also wise to verify any outstanding finance on the car, as this could affect ownership.
Bodywork
Inspect the bodywork for any signs of rust, dents, or mismatched paint. Pay special attention to the wheel arches and undercarriage. Ensure all doors and boot open and close smoothly. Check for any signs of previous accidents, which could affect structural integrity. Look for paint overspray or uneven gaps between panels, which might indicate poor repairs.
Engine Cold-Start
When starting the engine from cold, listen for any unusual noises. The engine should start smoothly without excessive cranking. Look for warning lights on the dashboard. Check for any leaks under the vehicle after a few minutes of running. Additionally, monitor the exhaust for excessive smoke, which could indicate underlying engine problems.
Test Drive Checklist
During the test drive, assess the engine’s performance. It should accelerate smoothly without hesitation. Test the brakes for responsiveness and listen for any grinding noises. Ensure the steering feels precise and check for vibrations at higher speeds. Also, test the vehicle’s handling around corners to ensure it remains stable and responsive.
Gearbox
For automatic models, the gearbox should shift smoothly without jerking. In manual versions, ensure the clutch engages easily and the gears change without grinding. Listen for any unusual sounds during gear changes. It is also beneficial to check how the gearbox reacts during different driving conditions, such as stop-and-go traffic or highway speeds.
Electrics
Check all electronic features, including windows, lights, and infotainment systems. Ensure the air conditioning works effectively. Test the reversing camera and parking sensors if equipped. A malfunctioning infotainment system is a common issue in older models. Additionally, check the functionality of the keyless entry system, as some owners have reported issues with this feature.
MOT History
Review the MOT history for any recurring issues or failures. This can provide insight into the vehicle’s condition and help you avoid future problems. Use the DVSA website to access this information easily. Look for any advisories that may indicate potential future repairs or concerns.
Use Honest Car Check to verify mileage and MOT history. This will help ensure you are making a confident decision before purchasing a used Lexus NX.
