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 US$54,270 in the US market, down 11.3 percent over the past twelve months, with a sell signal indicating downward pressure in the near term.
Market activity for this model remains sparse, with no tracked sales in the past year and no active listings currently available. This illiquidity constrains price discovery and makes transaction timing difficult for both buyers and sellers in either direction.
The Sierra RS Cosworth carries a collectibility score of 6 and is classified as an appreciating classic, though current desirability registers as low. This mismatch between classification and present-day demand suggests the market has not yet consolidated around a stable collector base for these cars in the US.
The three-year base projection shows a decline to US$41,274, representing a 23.9 percent loss from current levels. Over five years, prices are forecast to settle near US$37,905, a cumulative 30.2 percent drop from today's median, reflecting sustained softness in collector interest.
The combination of minimal transaction volume, negative momentum, and downward price forecasts creates an uncertain backdrop for ownership. Until trading activity picks up materially or desirability shifts, the market remains difficult to read with confidence.
