No direct experience, believe me, but I can only imagine that they'd ask for a statement of net worth before giving you an appointment, and even if you didn't send one in, they'd charge you what they think they can extract from you. I may be a bit crazy and foggy in the memory, but I think I came across something a few years back, maybe in one of the better car magazines, that said a major service cost $1200. Certainly check this out further, I imagine the pricing has more to do with the model of car rather than the actual work done it (he said cynically).
