Premiums compare the median price of sales with each option against comparable sales without it, mined from verified auction listings. Prices are adjusted to the model's median mileage before comparing. 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 928 market has contracted sharply, with the median price dropping to $23,806—a 20.1% decline over the past twelve months. The sell signal reflects this sustained depreciation and suggests momentum remains downward in the near term.
Transaction volume remains modest at twelve sales tracked over the past year across a total dataset of twenty-nine cars, indicating moderate liquidity. This thin sample size means individual sales can sway data, though it also reflects a narrower buyer pool actively seeking these cars.
As a stable modern classic with over 61,000 units produced, the 928 occupies a broad supply tier that constrains collectibility appeal. The modest demand rating reflects the car's position as a driver-focused alternative to contemporary Porsches rather than a scarcity-driven collectible.
Cars in the market are averaging 65,750 miles, typical for vehicles now in their third or fourth decade of ownership. This mileage profile suggests most transacted examples are honest drivers rather than garage queens.
The three- and five-year outlook projects no appreciation, with prices holding near current levels at $23,806. The absence of upward catalysts, combined with the large production run and steady depreciation trend, points to a stabilization phase rather than recovery in the medium term.
