Audi S4 (C4)

The Audi S4 C4 currently trades at a US$15,500 median, though the thin transaction history—just three sales tracked over the past year—limits confidence in establishing a reliable price trend or directional signal at this time.

Liquidity remains constrained, with only a single active listing and sparse sales activity across the tracked market. This thin trading volume means buyers and sellers should expect extended search periods and may face wider spreads between asking and actual sale prices compared to more liquid segments.

The C4 S4 occupies a collectible tier with inherent appeal among enthusiasts, though desirability remains low relative to other modern classics. Production data is not available, but the model's position in the market suggests it commands modest collector interest without commanding premium valuations.

Transacted examples average approximately 94,000 miles, which is moderate mileage for vehicles in this age bracket and generally reflects cars that saw regular use rather than garage storage.

Without sufficient transaction history, year-over-year pricing trends and forward projections cannot be reliably established. A larger sample size and more consistent market activity would be needed to identify whether the C4 S4 is appreciating, depreciating, or holding value over a three-to-five-year horizon.
