The STLL SLO Audi S4 is a 2001 laser red sedan that has been owned by Stephen since the fall of 2008. It was purchased bone stock and did not stay that way for very long. It has been through many states of modification over the 16+ years of ownership and will most likely continue to evolve. With 85,000+ big turbo miles out of almost 190,000 on the chassis, it is time for some BIG improvements to reliability.
