This 2005 Audi S4 Avant, with 98k miles, features a 4.2-liter V8 and a six-speed manual transaxle with Quattro all-wheel drive. Notable modifications include Rotiform 18" wheels and an aftermarket Pioneer stereo, while significant maintenance includes a timing chain replacement in 2019. The car has a clean Colorado title, though the Carfax reports an accident in 2005, and there is noted seepage from a valve cover gasket.
