[Huh]

just be careful with the S4s. Make sure that the turbos are in good shape. They were known for failing because of the way the oil fed into the turbo. 2002 and after were fixed for the problem. See if the oil lines have been fixed or turbos replaced. They had such potential for high hp so many of them were chipped. Just have it checked out by your porsche wrench if you don't know much about the car. I am more in tune to VWs and Audis. It will take some time for the Porsche on a mechanical level.
