If you haven't already found the right mechanic, I highly recommend Sean Ratts. Check out 928docs.com His email is: Sean@928docs.com He may have a waiting list, as he's building a new facility and it won't be done for a couple of months. Tell him I recommended him!!
You will also want to get acquainted with Roger Tyson - supplier of parts worldwide - who is located in the Dallas area: 928sRus.com is his business web site. Lots of 928 owners in that area.
Welcome to the Club of 928 owners.
