This 2007 Audi RS4 (B7) with ~102k miles is offered for $12,000 OBO, though it requires engine work due to a tentative diagnosis of rod bearing failure. It has been exclusively serviced by RS4 specialists for 12 years, comes with extensive documentation, and features numerous modifications including Bilstein PSS9 coilovers and a JHM Motorsports tune. The car has a clean title, two minor front-end incidents (one not on Carfax), and includes two wheel sets and an upgraded head unit.
