Understanding Audi S4 Depreciation: How Value Changes Over Time

When evaluating the used Audi S4 price, a number of factors drive its depreciation curve. For many premium sports sedans from the 1998 era, the life cycle follows a predictable pattern:

• First Year: Loss of 15‑20% of the original purchase price—typical for high‑performance vehicles with significant technology upgrades.
• Years 2‑3: Roughly 10‑12% per year, as the car moves from a new to a used status and cumulative mileage increases.
• Years 4‑6: Depreciation slows to 7‑8% per year, largely driven by the car’s reputation for durability and the maintenance of original features.
• After Year 7: Consistency drops to 4‑5% per year, with value mainly influenced by market sentiment and owner maintenance records.

Because the Audi S4 depreciation trend is highly data‑dependent, comparative studies of wear-and-tear volumes, engine oil consumption, and component replacement costs show a stroller-accelerated decline for early models that weighed heavily on the turbo and used older timing components. Buyers who appreciate the classic twin-turbo layout often accept a slightly higher price if the car has completed a quiet service history, especially within the 6‑range to 12‑range year bracket (estimated current market price ranges tend to fluctuate from rarely low $10k to high $15k).
