Please let me know how you make out. I have a 6.9 and I am also in Fredericksburg. I've had a terrible time getting any local shop to even look at my car. As soon as they hear what model it is, they politely ask me never to bring it to their shop.
I've been doing all the work myself, but I just know there is going to come a time when I simply won't be able to do the work myself.
