Well, are you able to actually see it in person? 1700 is a lot to plop down without actually seeing the bike. A v&h is a good exhaust and it looks like a nice bike but you really want to be able to check things out. If everything is in good shape and you like the bike, then 1700 might be good. Maybe counter offer 1500 and see what happens. If it has been listed for a while, they might go for it.
The ride IS the adventure. The destination is just to get gas!
