Buying Tips for the McLaren 12C

  • A harsh or floaty ride often points to tired ProActive Chassis Control accumulators rather than a simple alignment issue
  • Check very carefully for coolant smells, damp radiators, or evidence of hose-clamp updates because early cars can lose coolant slowly
  • Test IRIS, nose-lift, parking sensors, and both dihedral doors repeatedly because electrical niggles matter on cars that have sat unused
  • Prefer cars with recent specialist maintenance over ultra-low-mileage examples that have spent long periods parked
