Dealing with the seller: Do NOT make an opening offer on the phone. As you've probably guessed, he'll take that to be "another time waster" and hang up. If you're seriously interested in the bike, at least have the courtesy to take the time and go see it. Then start dickering.
I know that when I sell, if I get a call that opens with, "I'm interested in your bike, where is it, and when would be a convenient time to see it?", I've got someone to take at least semi-seriously. Odds are, we'll come to a deal, even if it is a few bucks under what I'd really like to get for it.
Attitude is everything, especially in a business transaction.
Assuming that the 760 ride like the 460 I recently got (same family and design, if not the same tubing) you're going to love it.
