Audi S4 (C4)

The C4 S4 is trading at a median of $4,200 in the current market, though confidence in this valuation is limited by minimal transaction activity.

Liquidity remains a significant constraint, with only one tracked sale over the past 12 months and no active listings at present. This level of trading activity makes it difficult to establish reliable pricing signals or detect meaningful directional trends.

The C4 S4 carries a collectible rating despite low desirability metrics, positioning it as a niche segment within the modern classic category. Production volumes and original MSRP data are not available, limiting further context on rarity or relative affordability versus period alternatives.

The scarcity of recent transaction data—a single sale in our sample—means buyers and sellers should expect extended search periods and potentially volatile individual pricing depending on specific car condition and provenance. Without multiple recent comps, pricing negotiations will likely rely heavily on comparable models from adjacent model years or related Audi sport platforms.

No three- or five-year projections can be reliably established given the absence of sustained trading history. Meaningful market signals will only emerge once transaction frequency increases enough to reveal underlying demand or supply shifts in this segment.
