Condition:

This B5 S4 exemplifies the well-kept, heavily upgraded enthusiast build—featuring a full suite of respected Stage 3+ mods, extensive documentation, and major recent maintenance to both drivetrain and suspension. The car benefits from top-tier modifications with supporting hardware, and aesthetic presentation is respectable for age, with most exterior/interior elements showing only moderate wear, but key points of body corrosion (door, trunk) will require attention sooner rather than later to avoid further spread. The undercarriage and suspension show cosmetically heavy rust typical of cars exposed to northeastern winters, but nothing in the photos or documentation indicates immediate structural concerns. The headliner, keyless entry, and airbag light are the main cabin faults noted. Tires must be replaced before spirited driving due to flat spotting, but brakes, engine, and clutch assemblies are robust and recently serviced.

Valuation:

Considering the extensive enthusiast modifications, strong maintenance records, and present mechanical health, but also taking into account the visible body rust, prior accident repair, and interior issues, this car squarely fits into the “fair/driver” category. Supporting auction results for high- mile, modified, non-pristine B5 S4s in similar spec (e.g., the 2001 S4 with 119k miles at $8,750 and the 2002 with 146k miles at $7,500) confirm this. Values trend toward the lower end for examples with corrosion and cosmetic flaws, while high-mile drivers with tasteful mods and documentation have sold for $7,500–$9,500. With the current body corrosion and needed cosmetic work, this car’s fair value is modestly discounted from a “good” condition car.
