Radar Report

Our view on this set, in plain English.

Collector Confidence 52%WATCH ONLY

Too early — margin is thin at this price

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.

Future value prediction

£205

Projected upside

24%

Expected timeframe

30-48 months

Deal quality & demand

  • 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.

Potential upside

Short-term flip potential

Fees erase the margin at current pricing.

Weak

Medium-term growth potential

Expect further softening before supply tightens.

Neutral

Long-term collector value

Licensed supercars recover well several years after exit.

Positive

Great set, wrong moment — wait for the mid-life price trough.
