Equipment buyers should verify
Factory identity
Verify fixed-back buckets or adaptive seats, PCCB or steel brakes, Sport Chrono, and extended-range fuel tank.
Chassis and controls
Confirm original GT4 wheels, front splitter, rear wing, suspension, exhaust, and retained OEM parts.
Cabin and trim
Review over-rev data, clutch and gearbox condition, brake wear, alignment history, and track use.
Retained hardware
Use the option sticker or build sheet to distinguish a coherent factory specification from later cosmetic additions.
Documentation signals
Strong evidence
Specialist care and consumables history. Transparent track-use or driver-use narrative. PPI confirming aero, chassis, and brake correctness.
Reasons for caution
Dealer-marketed rarity language without records. Wheel, brake, or suspension changes with no OEM return path. Overheated low-mileage pricing on average-condition cars.
