If you are in the Cincy are there is a good independent European car repair shop. they work on EVERYTHING, they are a small shop, most of the mechanics have been there for ages, no turn over in that dept. Honest folks.
They have worked on both of my XK8's I have owned, my brother has had them work on his Jags and old VW bugs.
