2025 Caterham Unknown 1.6L Petrol · Q986 NRS

An intermittent failure regarding exhaust emissions and windscreen integrity characterizes the recent testing history, though the vehicle returned to a clean status by its latest inspection on 29 September 2026. The record shows a period of instability in early 2026 when a failure was recorded due to excessive carbon monoxide emissions and a cracked nearside windscreen. While the subsequent pass indicates these specific issues were rectified, the presence of a major emission failure within a very young vehicle warrants a close examination of the engine's combustion efficiency and exhaust system integrity. The recorded mileage of 1,699 miles suggests a very low annual accumulation rate for a vehicle of this age. This usage profile indicates the car has been driven sparingly, averaging less than 1,700 miles per year. From a mechanical standpoint, such low mileage means that primary drivetrain and suspension components will likely show minimal physical wear, but it also increases the possibility that the vehicle has spent significant periods stationary. Long intervals between use can sometimes lead to issues with fluid stagnation or component seals, though the recent passing of the MOT without further defects suggests no immediate systemic issues have emerged from this usage pattern. Prospective buyers should focus their physical inspection on the exhaust and emissions-related components to ensure the previous carbon monoxide failure was fully resolved. During a test drive, pay close attention to the engine's idle quality and listen for any irregular hunting or rough running, which could indicate lingering issues with the fuel mixture or sensor readings. It is also advisable to monitor the exhaust note for any unusual sounds, such as leaks or pulsations, that might suggest the exhaust system is not sealing correctly. Regarding the previously noted windscreen damage, a thorough visual inspection of the glass is necessary to ensure no new cracks or chips have developed near the edges or within the driver's field of vision. While the MOT record is currently clear of advisories, the combination of low mileage and a previous emission failure means the buyer should verify that all sensors and electronic control units are functioning as intended to maintain the correct air-fuel ratio. Focus on the smoothness of throttle response and the absence of any hesitation during acceleration to confirm the vehicle's combustion stability.
