This 2006 Audi S4 Avant features a replacement supercharged 4.2-liter V8, a six-speed manual transaxle, and extensive modifications including Öhlins coilovers, Wavetrac limited-slip differentials, a JH Motorsports big brake kit, and carbon-fiber accents. Showing 87k miles, the car has received recent supercharger maintenance and other services, though it has a ding on the right-front door, chips on the front bumper, and a reported clunk from the right-rear suspension.
