2009 Mitsubishi Colt 1.5L Petrol · RB02 TJB

The most recent MOT test on 10 November 2025 resulted in a pass, but it is important to note that this pass was achieved only after a prior failure on the same date, which cited both rear coil springs as Major defects due to corrosion reducing their cross sectional area and seriously weakening them. This represents a significant and progressive decline in the rear suspension condition, with advisories for both rear coil springs first appearing in 2023, repeating as advisories in 2025, and then escalating to Major failure items before being resolved for the pass. The overall maintenance trend is therefore worsening rather than stable, particularly concerning the rear axle corrosion, while the brake and tyre advisories from earlier tests show a similarly recurrent pattern of surface deterioration consistent with age and possibly periods of standing. The recorded mileage of 93,135 miles over approximately 17 years equates to an annual average of around 5,479 miles, which is notably low for a vehicle of this age. This low usage figure suggests the Colt has either covered modest distances regularly or has experienced extended periods of inactivity, both of which carry their own mechanical implications. Infrequent use typically accelerates corrosion on ferrous components such as brake discs, calipers, exhaust mounting brackets, and underbody steel, while placing cyclical strain on the 12 volt battery, which degrades rapidly when not kept fully charged. Low annual mileage also means that time based service items such as brake fluid, coolant, and gearbox or differential oils are likely to have degraded through age rather than mileage, and verifying their replacement dates via the service history is essential. Given the recurring rear coil spring advisories and the ultimate failure on both springs, a prospective buyer should thoroughly inspect the rear suspension on a physical hoist or ramp for any further corrosion, cracking, or flattening of the springs, and listen for clonks or thuds over uneven road surfaces during a test drive. The rear axle should also be examined for related corrosion to the shock absorber bodies, mounting bushes, and trailing arm components, as these tend to deteriorate in tandem on a vehicle of this age. The brake discs were advised for replacement in 2021 and 2022 due to corrosion and pitting, so confirm whether this work was completed, as neglected discs can produce brake shudder, vibration under heavy braking, or uneven pad wear. During a test drive, listen for any scraping or grinding, feel for pulling to one side, and check for binding calipers by ensuring the wheels rotate freely when jacked and by monitoring whether the car rolls straight when released with the handbrake off. Beyond the documented MOT items, the age and low mileage profile of this Colt warrant close attention to several time related wear factors. Inspect all sidewalls and the sidewall to tread junction for perishing or cracking, as tyre rubber degrades with calendar age regardless of tread depth, and any tyres older than six years should be replaced on safety grounds. Examine the exhaust system along its full length for rust perforation, paying particular attention to the rear silencer box, mounting rubber, and the joint between the manifold and downpipe, as these are known corrosion points on older Mitsubishis. Check the 12 volt battery state of charge and load test it if possible, as a battery that has stood for long periods will have reduced capacity. Verify the service book stamps or digital records to confirm regular oil and filter changes at least annually, and ask for evidence of brake fluid, coolant, and any automatic or manual transmission fluid replacement. Finally, inspect the underbody and inner wheel arches thoroughly for surface corrosion, ensuring that structural integrity remains intact and free from advanced rot around sills, jacking points, and suspension turrets.
