Cyndi,
I've had good luck at the dealer on Shelbyville Rd, although I have not been there since they changed ownership. They were always accomodating and went to bat for me on a couple of warranty issues (and got it done!). Of course, they're not cheap.....
If you have any of your scheduled maintenance done there 15k, 30k, etc service, make sure to give them a list of what you want done instead of relying on their standard service pack. They omit some things the VX requires, and add a whole lot of useless (revenue building) items. Good luck!
