Audi S4 (C4)

The C4 S4 remains thinly traded in the US market, with only a single transaction recorded over the past year at a median price of $4,200. The extreme scarcity of sales data means any price signal should be treated as indicative rather than definitive for this segment.

Classified as a stable modern classic, the C4 S4 occupies a narrow collectibility tier that recognizes its mechanical and historical significance without commanding broad market enthusiasm. The "low desirability" designation reflects modest buyer demand relative to contemporary performance alternatives and more celebrated Audi models.

Illiquidity remains the defining characteristic of this market. With zero active listings and only one tracked sale annually, sellers and buyers should expect extended holding periods and limited negotiating leverage when transactions do occur.

Without transaction volume sufficient to establish reliable mileage baselines or directional pricing trends, the $4,200 level represents a data point rather than a trend. Prospective buyers and sellers operating in this segment should rely on mechanical condition, provenance, and original equipment specifications as primary value drivers given the absence of robust comparable sales.
