It turns out that I did find a Great Independent Porsche Mechanic and I look forward to doing business with them in the future.
I had a great experience with Alan Kidson (owner) and Jerry Weiden (their Porsche Master Mechanic).
This was considered a major service by Porsche standards and Sean Freed did the work himself.
Great experience & convenient!
So, this is now the only Porsche shop I use.
Matt Armstrong is the best mechanic in cartersville Georgia.
