This 2004 Audi S4 Avant, with 161k miles, features a comprehensive mechanical refresh completed in August 2025, including a timing-chain service and transmission rebuild. It boasts numerous performance modifications such as Vogland coilovers, JH Motorsports catless headers, 18-inch Hartmann wheels, and upgraded Brembo six-piston front calipers. The car is finished in Brilliant Black over Black Silk Nappa leather and includes a clean Illinois title, though the Carfax report notes multiple past accident and damage entries, and there are some paint chips, scratches, and rust bubbles present.
