I am looking for an experienced Porsche shop for a PPI in Knoxville, TN. I would appreciate any recommendations you have, other than Harper Porsche. Nothing against Harper, I have heard that they do a good job. That's where the car has been serviced and I would like to use a shop where the car does not have a previous history, i.e. an evaluation by a fresh set of unbiased eyes.

Thanks in advance!
