I have never heard anything good about Royal Gate "neighbor" . In the future, I would stay away from them. While I've not had much other than an oil change, Glendale seems pretty good and they seem to appreciate the business.
On a side note, keep tabs on the mid-west section of the web site, thus far this is a small group of us getting together once in a while and would welcome just about everybody....who owns an XF that is.
You can always PM me or shark067 (he pretty much organizes everything). Pass the word if you know others.
