2011 Mclaren 12C 3.8L Petrol · AD61 VTE

This McLaren 12C has covered only 25,005 miles in roughly 15 years of ownership, averaging around 1,667 miles per year. That is exceptionally low mileage for a vehicle of this age and suggests either very light recreational use or extended periods sitting idle between drives. Both scenarios carry distinct implications for the mechanical condition. The most recent MOT from June 2025 shows a PASSED result, but with a notable advisory: both the nearside and offside rear brake discs are recorded as worn, pitted, or scored, though not yet seriously weakened. This is the first defect to appear across the entire five-year history provided. Prior MOTs in 2024, 2023, 2021, and 2020 returned no recorded defects, suggesting the brake disc wear has developed relatively recently—likely within the past year. The pattern here is important. Brake disc degradation on a low-mileage car is rarely driven by wear alone; it is far more commonly the result of corrosion and pitting caused by moisture, salt exposure, and inactivity. When a vehicle sits for weeks or months between uses, brake rotors develop rust and surface pitting that accumulates over time. This McLaren's extremely low annual mileage makes that scenario highly plausible.
