2006 Ford Mustang 4.0L Petrol · PL55 ENT

A 2006 Ford Mustang carrying two clean passes and a single failed submission with no recorded defects presents a positive roadworthiness track record, though the absence of advisory notes across every visit means there is limited granular evidence of component wear. The most recent test on 19 March 2025 returned a pass with no advisories, reinforcing a stable pattern rather than a gradual decline. That said, the failure logged on 7 June 2022 alongside a pass on the same date is unusual; it likely represents a same-day retest where an initial defect was rectified prior to the pass being issued. Without defect text on file, the specific nature of that intervention cannot be confirmed, so a buyer should treat the failure as a reminder to inspect the relevant system thoroughly before purchase. With just under 61,000 miles accumulated over twenty years, this Mustang averages around 3,050 miles annually, which is well below typical usage for a vehicle of this age and a clear indicator of light running. The 2022 test and the 2025 test sit roughly three years apart, suggesting the car was either stored, used sparingly, or used only in fair weather during the intervening period. Low annual mileage reduces wear on major drivetrain components such as the clutch, gearbox, and engine internals, but it raises the probability of deterioration in areas sensitive to standing still. Rubber components, including suspension bushes, drive belts, hoses, and tyre sidewalls, tend to perish and crack from lack of flexing, while brake discs and pads can develop surface corrosion that leads to judder or uneven feel on the first application. A prospective buyer should therefore focus on the silent failure of 2022 by physically verifying the system involved; common candidates on a Mustang of this era include the exhaust, emissions sensors, or braking components, so a thorough check of exhaust integrity under the car, a visual inspection of brake discs for lip corrosion, and a scan for any warning lights on the dashboard would be prudent. Beyond that, given the modest mileage, a careful inspection of all suspension linkages, anti-roll bar bushes, and coil springs is warranted, as these can suffer from dry rot even when mileage is low. On a test drive, listen for clonking noises from the front suspension over speed humps and uneven surfaces, which would indicate worn bushes or top mounts. Further checks should target the braking system response, steering behaviour, and any signs of fluid leaks that may have developed during periods of inactivity. The pedal should feel firm and progressive without excessive travel, and the car should pull up in a straight line without pulling to either side. Steering should remain tight without slack at the centre or any knocking when turning the wheel on full lock, as this can point to worn tie rod ends or power steering components. Finally, request evidence of recent fluid changes covering the engine oil, brake fluid, and coolant, as low-mileage cars are frequently neglected in these areas due to perceived low wear, and any evidence of weeping around the sump, radiator, or power steering rack should be treated as a negotiating point or a priority repair.
