2007 Audi RS 4

Left mechanically stock aside from an exhaust system and a carbon fiber lip, this B7 RS 4 appears to be in excellent shape. The upgraded Milltek exhaust adds a little power, but more importantly it lets the high-revving 4.2L V8 be heard as it revs all the way through 8,000 RPM. It benefits from new brake pads and rotors, and the tires are nearly new and have plenty of meat left on them.
