2015 Mclaren 650S 3.8L Petrol · SH14 RES

The 2015 McLaren 650S presents a stable and consistently clean roadworthiness record. The most recent MOT test, conducted on 3 February 2026 at 9,387 miles, passed with zero defects recorded. This outcome mirrors every prior test in the available history, indicating no recurring mechanical or structural faults and a maintenance trend that remains firmly stable rather than worsening or improving. The mileage pattern is notably low for an eleven-year-old vehicle. Annual accumulation averages roughly 853 miles, with the odometer climbing only 340 miles between the August 2024 and February 2026 tests. A significant gap exists between the May 2021 test at 4,461 miles and the March 2022 test at 8,394 miles, representing a jump of 3,933 miles in just over ten months after a period of minimal use. This suggests the car stood largely idle before 2021 and has since seen slightly more regular but still very light annual mileage. Despite the clean MOT record, a buyer should physically inspect components that low-mileage storage can degrade independently of MOT failure criteria. Suspension bushes, coil springs, and dampers may show age-related deterioration or dry cracking from prolonged standing rather than mileage wear. Tyres, brake discs, and calipers deserve close attention; a car covering fewer than 400 miles per year is prone to surface corrosion on brake rotors and potential caliper seizure, neither of which always triggers an advisory on a short test drive. The exhaust system, fuel lines, and rubber hoses should be examined for perishing caused by age rather than use. On a mid-engined McLaren of this generation, verifying the structural integrity of the engine bay and underbody for corrosion or fluid leaks remains prudent, particularly given the extended dormant periods implied by the mileage data. A clean MOT history is encouraging, but the service record and evidence of regular fluid changes will matter as much as the roadworthiness tests themselves.
