This 2003 Audi RS6 features a 6-speed manual transmission swap, a tuned 4. 2L DOHC twin-turbo V8 producing 489 horsepower, and numerous modifications including ST coilovers, Hotchkis sway bars, larger intercoolers, and RS4 19” wheels. Recent service included replacing the left-side turbocharger and a more comfortable clutch, though the car has noted dings, curb rash, and a 2013 Carfax incident affecting the passenger-side front.
