Premiums compare the median price of sales with each option against comparable sales without it, mined from verified auction listings. Sales are pooled across markets on a relative-price basis, so exchange rates and market levels can't skew the split. Options interact in ways a one-at-a-time split can’t capture — treat each premium as directional rather than gospel.

Marque analyst note

The Ford Sierra RS Cosworth is trading at a median of AUD $82,227 in the Australian market, having declined 11.3% over the past twelve months. The sell signal reflects underlying weakness, though confidence in the trend is moderate given extremely thin transaction activity.

Liquidity remains a critical constraint on this model, with only a single sale tracked over the past year and no active listings currently available. This scarcity of transaction data limits visibility into true market demand and makes pricing highly dependent on individual circumstances rather than broad collector sentiment.

Desirability is currently assessed as low, which stands at odds with the car's historical significance as a homologation special and road-going performance icon. The mismatch between collectibility score and current appetite suggests the model has lost favor in the present Australian market cycle.

Forward projections show material pressure ahead, with the base case forecasting a decline to AUD $62,536 over three years (−23.9%) and AUD $57,432 over five years (−30.2%). These downside estimates reflect both the illiquid trading environment and the absence of near-term catalysts to reverse the negative momentum established this year.

Prospective buyers should recognize that entry at current levels offers no margin of safety given the sparse transaction history and continued depreciation path. Sellers holding inventory face a narrow window for exit before further softening takes hold.
