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 is holding at a median of AUD$58,000 in the Australian market, down 1.8 percent year-on-year—a modest decline that reflects the model's stable but uninspiring momentum. The HOLD signal suggests no urgent directional pressure, though the slight downward drift warrants monitoring.
Only five transactions have moved through the tracked sample over the past 12 months across eight total recorded sales, indicating a thin liquidity environment. This sparse trading frequency means pricing tends to be opportunistic rather than consensus-driven, and buyers or sellers should expect extended holding periods or negotiation flexibility.
With 61,056 units produced across its production run, the 928 occupies the middle ground between everyday classics and genuinely scarce Porsches. Classified as a stable modern classic with modest collector demand, the model lacks the emotional pull or rarity that typically sustains value in the collectible segment.
The base case projection suggests a further 4.3 percent decline over three years and 5.7 percent over five years, settling around AUD$55,500 and AUD$54,700 respectively. This gentle depreciation reflects neither speculative appetite nor panic, instead tracking a car that fills a practical rather than passionate niche in the classic market.
