2006 Mazda MX-5 2.0L Petrol · FE06 SSX

The most recent MOT record shows a pass with no defects as of March 2022, but the overall maintenance trend reveals significant concerns regarding structural integrity. The vehicle has a history of major failures related to severe corrosion on the inner sills and the rear floorpan in both 2019 and 2022. While the car has successfully passed subsequent inspections, the recurring nature of these structural defects suggests that the vehicle has been prone to significant rust issues. The maintenance history is somewhat volatile, moving from major structural failures to clean passes, which necessitates a very cautious approach to its long-term roadworthiness and the quality of any previous repairs. With 119,823 miles recorded over approximately 20 years, the vehicle has averaged roughly 6,000 miles per year. This is considered low mileage for a vehicle of this age, suggesting it has been used sparingly or has spent extended periods stationary. While this may mean the engine and drivetrain have seen less mechanical wear than a high-mileage equivalent, low usage often brings its own set of risks. Long periods of inactivity can lead to the degradation of rubber seals, the settling of contaminants in the fuel system, and accelerated corrosion in areas where moisture is trapped, which aligns with the documented sill and floorpan issues. A prospective buyer must prioritise a thorough inspection of the vehicle's underside. Given the previous major failures for holed sills and corroded mounting areas, you should look for evidence of recent welding, patch repairs, or thick layers of underseal that might be masking ongoing structural decay. Check the sills, floorpan, and suspension mounting points for any signs of bubbling paint or active oxidation. During the test drive, pay close attention to the rear of the car; listen for any knocks, clunks, or unusual vibrations from the suspension, which could indicate that the structural integrity of the mounting points is still compromised or that the previous repairs are not providing sufficient rigidity. Furthermore, because the vehicle has been driven infrequently, you must check for age-related degradation of consumables. Inspect the tyres for sidewall perishing or cracking, as rubber components can fail due to age even if the tread depth appears sufficient. Examine the brake discs for heavy corrosion or pitting and ensure the calipers are not binding due to inactivity. It is essential to verify the service history to ensure that essential fluids, including brake fluid and coolant, have been replaced according to a calendar-based schedule rather than solely on mileage. Finally, check the condition of all rubber bushes and anti-roll bar linkages to ensure they have not perished from age and lack of regular movement.
