This 2000 Audi S4 has been adult owned and driven since day one. It has a chipped computer and an exhaust system designed by UUC Motorwerks. This makes for an S4 that is just as reliable as stock, but faster with a slightly more aggressive exhaust note. The car also has a custom front bumper, which provides for a unique look. The suspension and bushings were just recently replaced as a preventative maintenance.
