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 Porsche 928 in the Australian market is trading at a median of AUD $58,000, down 1.8 percent over the past year, with a hold signal suggesting current valuations reflect fair equilibrium. The modest negative momentum sits against a stable classification, indicating the model is neither appreciating nor deteriorating sharply in collector favor.

Supply is not a constraint: with 61,056 examples produced across its production run, the 928 occupies the broad middle ground of Porsche's output, which naturally limits upside for scarcity-driven appreciation. The car ranks at collectibility score 4 with modest demand, and desirability remains low—typical for front-engine Porsches that lack the cultural cachet of the 911 or the investment trajectory of air-cooled variants.

Liquidity remains thin across the Australian market, with only five tracked sales over the past twelve months and eight total in the dataset. The absence of current active listings suggests supply may tighten temporarily, but the low turnover reflects constrained buyer interest rather than scarcity value.

Base projections trend modestly downward: analysts expect AUD $55,495 (down 4.3 percent) by year three and AUD $54,721 (down 5.7 percent) by year five. Depreciation drivers include aging electrics, climbing maintenance costs, and persistent competition from newer Japanese sports cars in the secondhand market.

For buyers seeking entry into 928 ownership at fair value, current levels offer reasonable entry without expectation of appreciation. Prospective sellers should recognize the market's measured disinterest and price accordingly.
