2017 Smart (mcc) Fortwo 0.9L Petrol · OU17 RNF

The most recent MOT test for the 2017 SMART Fortwo was conducted on 2026-03-18 and resulted in a clean pass, indicating no defects were recorded. However, the vehicle’s MOT history reveals a pattern of recurring issues, particularly with the exhaust system, which caused two major failures in 2024 and 2025. The 2025 MOT failure highlighted both a major exhaust leak and a nearside rear tyre with a deep cut reaching the ply, while the 2024 test noted a minor exhaust leak and the same tyre defect. Though the latest test passed, these prior failures suggest a persistent underlying problem with the exhaust system and potentially compromised tyre integrity, warranting careful scrutiny of the vehicle’s long-term reliability. The fact that the vehicle has only recently passed an MOT without defects may reflect either a temporary resolution of the exhaust issue or a coincidence, but the buyer should remain vigilant for persistent exhaust emissions or unusual noises from the exhaust manifold or catalytic converter. The vehicle’s recorded mileage of 21,258 miles over approximately nine years represents an annual usage rate of around 2,362 miles, which is notably lower than the average for its age. Such a low mileage could indicate infrequent use, long periods of stationary storage, or a vehicle maintained in a less demanding environment. However, lower mileage does not automatically equate to better mechanical condition, as prolonged idling or exposure to outdoor elements can accelerate wear on components like the exhaust system, tyres, and electrical systems. For example, standing for extended periods can lead to brake disc corrosion, binding calipers, or even fluid degradation in the cooling or hydraulic systems. Additionally, the vehicle’s age and the potential for previous maintenance gaps mean that consumables such as brake pads, suspension bushes, and timing belt components may have reached or exceeded their service intervals without recent servicing. Given the history of exhaust-related failures and the deep tyre cut recorded in prior MOTs, the prospective buyer should prioritise a thorough inspection of the exhaust system for signs of corrosion, cracks, or structural weakness around the manifold, catalytic converter, and exhaust pipes. Listen for unusual noises during the test drive, particularly when accelerating or braking, as these could indicate a failing catalytic converter, exhaust leak, or even a minor exhaust pipe fracture. The nearside rear tyre failure suggests that the tyre may have been subjected to excessive wear or damage, potentially from underinflation, improper alignment, or road debris. Inspect the tyre for any remaining cuts, bulges, or uneven wear patterns, and ensure the tread depth meets legal requirements. If the tyre has been replaced recently, verify the replacement date and check for any signs of internal damage, such as cord exposure. Beyond the exhaust and tyre concerns, the buyer should also address the vehicle’s overall roadworthiness by checking for standing corrosion on the chassis, particularly around the wheel arches, undercarriage, and door seals, as prolonged exposure to moisture can accelerate rust progression. Inspect the brake system for any signs of corrosion on the discs, binding calipers, or warped discs, which could indicate prolonged stationary use. Test the brakes by applying firm pressure during a slow deceleration to check for excessive vibration, grinding noises, or a spongy pedal feel, which may signal worn brake pads or hydraulic issues. Additionally, given the vehicle’s age and the potential for infrequent servicing, examine the 12V battery for signs of weakness, such as a slow crank or dimming lights, and ensure the alternator is functioning correctly to maintain charge levels. Finally, check the fluid levels—particularly the engine oil, coolant, and brake fluid—for any signs of degradation or contamination, as these fluids can break down over time regardless of mileage. If the vehicle has been stored for extended periods, consider a comprehensive fluid refresh and a check of the suspension components for stiffness or play, as standing can cause bushings and springs to stiffen or fail prematurely.
