PPI Austin

You might try either of the Audi dealers here. Audi North Austin, Audi South Austin. If you are looking for an independent, then you could try Moorespeed, Calvo Motorsports, or Boost Logic. Are you looking at an R8 from a dealer? As an R8 5.2 owner, and a 911 owner, I might be able to point you in the right direction, and might even know a little about the car you are looking at.
