I need to throw out a recommendation for Griffin Motorwerks in Berkeley.

I had just bought my V in '04 and had it for only a little over 2 months before driving a cross country trip. On the way, I got to hear the parade clunk for the first time. I was so nervous about it, I called these guys when I was out there since the Caddy dealer didn't want to touch it(After taking 6 hours and almost botching everything, the Caddy dealer finally got my oil temp reflash done).
They specialize in foreign cars but their reputation is excellent. When I got there, they really wanted to help with the problem. They put the V on their alignment lift had a tech in the car engaging the clutch while in the air, trying to replicate the problem. We figured out where it was coming from and they did extensive testing to make sure it was nothing more than noise and not a fatal problem.
They even put me in contact with different vendors who do custom fab work on trailing arms and end links and the like. Even though they had never worked on the V, they were sincerely interested in it and weren't closed minded. And they refused to take any money for the time. Now, their rates aren't cheap from what I've seen, but the reputation is worth it.
If I lived in the Bay Area, I'd go to them with all my suspension and alignment work, no question...
