Our view

A technically brilliant build with a licence collectors love, but the market is saturated. Heavy retailer stock and a recent release date mean the story hasn't started yet. Our radar is watching, not buying. At a 164.99 entry against a 178.00 secondary-market median, Brick Radar models a net loss of 23.41 per unit after marketplace fees, payment fees and postage — a -14.2% return on capital over a 30-48 months horizon.

Why we recommend this set

  • Collector demand: Genuine enthusiast interest, but buyers are patient and price-sensitive.
  • Rarity: Heavy stock levels across every tracked retailer.
  • Retirement potential: 12+ months before the retirement window even opens.
  • Historical performance: Flagship supercars typically dip below RRP mid-life before recovering.
  • Future resale appeal: Strong long-term display appeal once supply normalises.

Risks to watch

  • Retailer stock is still heavy — further discounting is likely before supply tightens.
  • Retirement is more than a year away, so capital would be tied up with no scarcity catalyst.
  • Marketplace and payment fees absorb most of the current spread — margin is thin.
  • Collector demand is moderate rather than urgent; expect slower sell-through.
