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 Porsche 928 median has fallen to $23,806, down 20.1 percent over the past twelve months, signaling material depreciation pressure in the current market.
Transaction volume remains sparse, with only twelve sales tracked over the past year and seventeen total in our database, reflecting moderate liquidity that favors patient sellers over quick exits. This thin trading activity limits pricing transparency and can create wide spreads between asking and actual selling prices.
The 928 occupies a stable modern classic tier with modest collectibility scores, driven by its 61,056-unit production run—too large to command scarcity premiums but substantial enough to sustain a viable secondary market. Desirability remains moderate, placing the model in a holding pattern rather than an appreciation trajectory.
Average mileage on transacted examples sits at 73,833 miles, typical for cars now forty to fifty years old and consistent with regular use rather than garage-kept investment vehicles. Condition variation likely explains much of the price scatter in available inventory.
The near-term outlook projects flat valuation at current median levels through 2029, with base case modeling suggesting neither appreciation nor further erosion over the three- and five-year horizons. This stability reflects the 928's positioning as a usable classic rather than a scarcity-driven collector piece, making holding costs and maintenance the primary financial considerations for ownership.
